phpinfo
(PHP 4, PHP 5)
phpinfo — Visualizza diverse informazioni sul PHP
Descrizione
int phpinfo
([ int
$what
] )Visualizza molte informazioni sullo stato corrente del PHP Queste includono informazioni sulle opzioni di compila del PHP, sui moduli, la versioen di PHP, informazioni sul server e sull'ambiente (se compilato come modulo), l'ambiente PHP, la versione di OS, percorsi, valori delle configurazioni base e attauli, intestazioni HTTP e la licenza del PHP.
Dato che ogni sistema ha una cofigurazione differente, phpinfo() viene comunemente utilizzato per verificare le impostazioni di configurazione e le variabili predefinite disponibili in un dato sistema. Inoltre, phpinfo() è utili come strumento di debug poiché visualizza tutti i dati EGPCS (Environment, GET, POST, Cookie, Server).
L'output può essere personalizzato passando una o più delle seguenti
costanti sommate a livello di bit
nel parametro opzionale what.
Le costanti, o i rispettivi valori, possono essere combinati
anche con l'operatore or.
| Nome (constant) | Valore | Descrizione |
|---|---|---|
| INFO_GENERAL | 1 | La linea di configurazione, php.ini luogo, data di compila, Web Server, sistema e altro. |
| INFO_CREDITS | 2 | PHP 4 Credits. Vedere anche phpcredits(). |
| INFO_CONFIGURATION | 4 | Impostazioni correnti e di base delle opzioni PHP. Vedere anche ini_get(). |
| INFO_MODULES | 8 | Moduli caricati e le loro impostazioni. Vedere anche get_loaded_extensions(). |
| INFO_ENVIRONMENT | 16 | Variabili d'ambiente disponibili in $_ENV. |
| INFO_VARIABLES | 32 | Visualizza tutte le variabili predefinite da EGPCS (Environment, GET, POST, Cookie, Server). |
| INFO_LICENSE | 64 | Informazioni sulla licenza di PHP. Vedere anche » faq sulla licenza. |
| INFO_ALL | -1 | Visualizza tutto quanto descritto. Questo è il valore dei default. |
Example #1 Esempio di uso di phpinfo()
<?php
// Visualizza tutte le informazioni, default: INFO_ALL
phpinfo();
// Solo le informazioni sui moduli
// phpinfo(8) visualizza il medesimo risultato
phpinfo(INFO_MODULES);
?>
Nota:
La visualizzazione di parte delle informazioni è disabilitata quando expose_php viene impostato a off. Queste includono i loghi PHP e Zend, e i credits.
Nota:
La funzione phpinfo() produce un testo normale anzichè un file HTML quando è utilizzata in modalità CLI.
Vedere anche phpversion(), phpcredits(), php_logo_guid(), ini_get(), ini_set(), get_loaded_extensions() e la sezione sulle Variabili Predefinite.

To extract all of the data from phpinfo into a nested array:
<?php
ob_start();
phpinfo();
$phpinfo = array('phpinfo' => array());
if(preg_match_all('#(?:<h2>(?:<a name=".*?">)?(.*?)(?:</a>)?</h2>)|(?:<tr(?: class=".*?")?><t[hd](?: class=".*?")?>(.*?)\s*</t[hd]>(?:<t[hd](?: class=".*?")?>(.*?)\s*</t[hd]>(?:<t[hd](?: class=".*?")?>(.*?)\s*</t[hd]>)?)?</tr>)#s', ob_get_clean(), $matches, PREG_SET_ORDER))
foreach($matches as $match)
if(strlen($match[1]))
$phpinfo[$match[1]] = array();
elseif(isset($match[3]))
$phpinfo[end(array_keys($phpinfo))][$match[2]] = isset($match[4]) ? array($match[3], $match[4]) : $match[3];
else
$phpinfo[end(array_keys($phpinfo))][] = $match[2];
?>
Some examples of using individual values from the array:
<?php
echo "System: {$phpinfo['phpinfo']['System']}<br />\n";
echo "Safe Mode: {$phpinfo['PHP Core']['safe_mode'][0]}<br />\n";
echo "License: {$phpinfo['PHP License'][0]}<br />\n";
?>
To display everything:
<?php
foreach($phpinfo as $name => $section) {
echo "<h3>$name</h3>\n<table>\n";
foreach($section as $key => $val) {
if(is_array($val))
echo "<tr><td>$key</td><td>$val[0]</td><td>$val[1]</td></tr>\n";
elseif(is_string($key))
echo "<tr><td>$key</td><td>$val</td></tr>\n";
else
echo "<tr><td>$val</td></tr>\n";
}
echo "</table>\n";
}
?>
Note: In order to properly retrieve all of the data, the regular expression matches table headers as well as table data, resulting in 'Local Value' and 'Global Value' showing up as 'Directive' entries.

This function parses the phpinfo output to get details about a PHP module.
<?php
/** parse php modules from phpinfo */
function parsePHPModules() {
ob_start();
phpinfo(INFO_MODULES);
$s = ob_get_contents();
ob_end_clean();
$s = strip_tags($s,'<h2><th><td>');
$s = preg_replace('/<th[^>]*>([^<]+)<\/th>/',"<info>\\1</info>",$s);
$s = preg_replace('/<td[^>]*>([^<]+)<\/td>/',"<info>\\1</info>",$s);
$vTmp = preg_split('/(<h2>[^<]+<\/h2>)/',$s,-1,PREG_SPLIT_DELIM_CAPTURE);
$vModules = array();
for ($i=1;$i<count($vTmp);$i++) {
if (preg_match('/<h2>([^<]+)<\/h2>/',$vTmp[$i],$vMat)) {
$vName = trim($vMat[1]);
$vTmp2 = explode("\n",$vTmp[$i+1]);
foreach ($vTmp2 AS $vOne) {
$vPat = '<info>([^<]+)<\/info>';
$vPat3 = "/$vPat\s*$vPat\s*$vPat/";
$vPat2 = "/$vPat\s*$vPat/";
if (preg_match($vPat3,$vOne,$vMat)) { // 3cols
$vModules[$vName][trim($vMat[1])] = array(trim($vMat[2]),trim($vMat[3]));
} elseif (preg_match($vPat2,$vOne,$vMat)) { // 2cols
$vModules[$vName][trim($vMat[1])] = trim($vMat[2]);
}
}
}
}
return $vModules;
}
?>
Sample Output:
[gd] => Array
(
[GD Support] => enabled
[GD Version] => bundled (2.0.28 compatible)
[FreeType Support] => enabled
[FreeType Linkage] => with freetype
[FreeType Version] => 2.1.9
[T1Lib Support] => enabled
[GIF Read Support] => enabled
[GIF Create Support] => enabled
[JPG Support] => enabled
[PNG Support] => enabled

[Timezone Database] => internal
[Default timezone] => America/Los_Angeles
[Directive] => Array (
[0] => Local Value
[1] => Master Value
)
[date.timezone] => Array (

)
)
<?php
/** get a module setting */
function getModuleSetting($pModuleName,$pSetting) {
$vModules = parsePHPModules();
return $vModules[$pModuleName][$pSetting];
}
?>
Example: getModuleSetting('gd','GD Version'); returns "bundled (2.0.28 compatible)"

big thanx 2 Mardy dot Hutchinson at gmail dot com
very good!
some fixes to correct result displaying:
1. we need to trim $matches [1], 'cause there can be empty lines;
2. not bad to remove <body> tag 'cause styles for it not apply correctly...
3. ...and change styles a little (remove "body" selector)
we need to change two lines:
<?php
preg_match ('%<style type="text/css">(.*?)</style>.*?(<body>.*</body>)%s', ob_get_clean(), $matches);
?>
to
<?php
preg_match ('%<style type="text/css">(.*?)</style>.*?<body>(.*?)</body>%s', ob_get_clean(), $matches);
?>
and
<?php
preg_split( '/\n/', $matches[1] )
?>
to
<?php
preg_split( '/\n/', trim(preg_replace( "/\nbody/", "\n", $matches[1])) )
?>
That's all! Now we have a really flexible addition to phpinfo();
Mardy dot Hutchinson at gmail dot com ¶

Embedding phpinfo within your page, that already has style information:
The phpinfo output is wrapped within a <div class='phpinfodisplay'>, and we privatize all the style selectors that phpinfo() creates.
Yes, we cheat on preparing the selector list.
<?php
ob_start();
phpinfo();
preg_match ('%<style type="text/css">(.*?)</style>.*?(<body>.*</body>)%s', ob_get_clean(), $matches);
# $matches [1]; # Style information
# $matches [2]; # Body information
echo "<div class='phpinfodisplay'><style type='text/css'>\n",
join( "\n",
array_map(
create_function(
'$i',
'return ".phpinfodisplay " . preg_replace( "/,/", ",.phpinfodisplay ", $i );'
),
preg_split( '/\n/', $matches[1] )
)
),
"</style>\n",
$matches[2],
"\n</div>\n";
?>
Perhaps one day the phpinfo() function will be modified to output such a safe string on its own.

here you can notice that these numeric values of phpinfo
are similar to certain things in the binary system:
-1, coded in 7 digits:
111 1111
look at this:
1+2+4+8+16+32+64=127
unsigned,127 is:
111 1111
so, take a look at this: the way to get all function is to add all of them. zero is nothing.-1 is all.
so you can pass option with a negative number.
for example:
<?php phpinfo(48) ?>
is also:
<?php phpinfo(-80) ?>
48 = 32 + 16
-80= 0 - 64 - 8 - 4 - 2 - 1
so you can see in negative mode it like that:
not nothing
not all (-1) don't forget it !
not option 64
not option 8
not option 4
not option 2
so, that's good if you don't want option 8, you will do this:
not nothing(0)
not all(-1)
not option 8(-1)
you got:
<?php phpinfo(-9); ?>
hope this will be useful, that's my 1rst post ^^

Hi.
Here my version of saving php_info into an array:
<?php
function phpinfo_array()
{
ob_start();
phpinfo();
$info_arr = array();
$info_lines = explode("\n", strip_tags(ob_get_clean(), "<tr><td><h2>"));
$cat = "General";
foreach($info_lines as $line)
{
// new cat?
preg_match("~<h2>(.*)</h2>~", $line, $title) ? $cat = $title[1] : null;
if(preg_match("~<tr><td[^>]+>([^<]*)</td><td[^>]+>([^<]*)</td></tr>~", $line, $val))
{
$info_arr[$cat][$val[1]] = $val[2];
}
elseif(preg_match("~<tr><td[^>]+>([^<]*)</td><td[^>]+>([^<]*)</td><td[^>]+>([^<]*)</td></tr>~", $line, $val))
{
$info_arr[$cat][$val[1]] = array("local" => $val[2], "master" => $val[3]);
}
}
return $info_arr;
}
// example:
echo "<pre>".print_r(phpinfo_array(), 1)."</pre>";

I needed a way to quickly scroll through the phpinfo which is a large list of information. so here it is. In the top there is a list with sections, the new section loaded extensions will hold the links to the anchors of the loaded modules. the section session variables will show the current loaded sessions. It's using Domdocument for manipulation so you should have that loaded:
<?php
ob_start();
$exts = get_loaded_extensions();
phpinfo();
$phpinfo = ob_get_contents();
ob_end_clean();
//print $phpinfo;
$html_str = $phpinfo;
$html = new DOMDocument();
$html->loadHTML($html_str);
$title = $html->getElementsByTagName("title")->item(0);
$title->nodeValue = "PHP Version ".phpversion();
$body = $html->getElementsByTagName("body")->item(0);
$body->setAttribute("style", "background-color:beige;");
$table = $body = $html->getElementsByTagName("table")->item(3)->nextSibling;
$head = $html->getElementsByTagName("table")->item(0)->nextSibling;
ob_start();
?>
<h2><a name="session_variables">Session variables</a></h2>
<table border="0" cellpadding="2" width="600">
<tr class="h"><th>Variables</th><th>Value</th></tr>
<?php foreach($_SESSION as $key=>$value){
if(is_bool($value)){
$value = ($value)?"true":"false";
}else if(is_array($value)){
$value = '<pre>'.print_r($value, true).'</pre>';
}else if(empty($value) && $value != "0"){
$value = "<i>no value</i>";
}
?>

I wanted a simple *function* to convert the output of phpinfo into an array. Here's what I came up with thanks to alot of the previous authors tips, and the source file: php-5.2.6/ext/standard/info.c
Call this function like phpinfo_array() prints the array, phpinfo_array(1) returns the array for your own processing.
== Sample Output ==
[PHP Configuration] => Array

Editable css for phpinfo() all what you need is change css properies...
<style type="text/css">
#phpinfo body, td, th, h1, h2 {font-family: sans-serif;}

This is necessary to obtain a W3C validation (XHTML1.0 Transitionnal)...
phpinfo's output is declared with that DTD :
- "System ID" has the wrong url to validate : "DTD/xhtml1-transitional.dtd" rather than "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"
- Some module names contains space and the function's output use the name in anchors as ID and NAME. these attributes can't be validated like that (unique name only).
<?php
ob_start ();
ob_start (); // Capturing
phpinfo (); // phpinfo ()
$info = trim (ob_get_clean ()); // output
// Replace white space in ID and NAME attributes... if exists
$info = preg_replace ('/(id|name)(=["\'][^ "\']+) ([^ "\']*["\'])/i', '$1$2_$3', $info);
$imp = new DOMImplementation ();
$dtd = $imp->createDocumentType (
'html',
'-//W3C//DTD XHTML 1.0 Transitional//EN',
'http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd'
);
$doc = $imp->createDocument (
'http://www.w3.org/1999/xhtml',
'html',
$dtd
);
$doc->encoding = 'utf-8';
$info_doc = new DOMDocument ('1.0', 'utf-8');
/* Parse phpinfo's output
* operator @ used to avoid messages about undefined entities
* or use loadHTML instead
*/
@$info_doc->loadXML ($info);
$doc->documentElement->appendChild ( // Adding HEAD element to HTML
$doc->importNode (
$info_doc->getElementsByTagName ('head')->item (0),
true // With all the subtree
)
);
$doc->documentElement->appendChild ( // Adding BODY element to HTML
$doc->importNode (
$info_doc->getElementsByTagName ('body')->item (0),
true // With all the subtree
)
);
// Now you get a clean output and you are able to validate...
/*
echo ($doc->saveXML ());
// OR
echo ($doc->saveHTML ());
*/
// By that way it's easy to add some style declaration :
$style = $doc->getElementsByTagName ('style')->item (0);
$style->appendChild (
$doc->createTextNode (
'/* SOME NEW CSS RULES TO ADD TO THE FUNCTION OUTPUT */'
)
);
// to add some more informations to display :
$body = $doc->getElementsByTagName ('body')->item (0);
$element = $doc->createElement ('p');
$element->appendChild (
$doc->createTextNode (
'SOME NEW CONTENT TO DISPLAY'
)
);
$body->appendChild ($element);
// to add a new header :
$head = $doc->getElementsByTagName ('head')->item (0);
$meta = $doc->createElement ('meta');
$meta->setAttribute ('name', 'author');
$meta->setAttribute ('content', 'arimbourg at ariworld dot eu');
$head->appendChild ($meta);
// As you wish, take the rest of the output and add it for debugging
$out = ob_get_clean ();
$pre = $doc->createElement ('div'); // or pre
$pre->setAttribute ('style', 'white-space: pre;'); // for a div element, useless with pre
$pre->appendChild ($doc->createTextNode ($out));
$body->appendChild ($pre);
$doc->formatOutput = true; // For a nice indentation
$doc->saveXML ();
?>
All that could be done with only RegExp but I prefer the use of DOM for manipulating documents

Removes sensitive data like AUTH_USER and AUTH_PASSWORD from the phpinfo output:
<?php
// start output buffering
ob_start();
// send phpinfo content
phpinfo();
// get phpinfo content

One note on the above functions for cleaning up the phpinfo() HTML and throwing it into an array data structure. In order to catch all of the info tidbits the preg_match_all has to be tweaked to deal with 2 and 3 column tables.
I have changed the preg_match_all() here so that the last <td></td> is optional
<?php
function parsePHPConfig() {
ob_start();
phpinfo(-1);
$s = ob_get_contents();
ob_end_clean();
$a = $mtc = array();
if (preg_match_all('/<tr><td class="e">(.*?)<\/td><td class="v">(.*?)<\/td>(:?<td class="v">(.*?)<\/td>)?<\/tr>/',$s,$mtc,PREG_SET_ORDER))
foreach($mtc as $v){
if($v[2] == '<i>no value</i>') continue;
$a[$v[1]] = $v[2];
}
}
return $a;
}
?>

same as above for configuration variables
<?php
function parsePHPConfig() {
ob_start();
phpinfo(INFO_CONFIGURATION);
$s = ob_get_contents();
ob_end_clean();
$a = $mtc = array();
if (preg_match_all('/<tr><td class="e">(.*?)<\/td><td class="v">(.*?)<\/td><td class="v">(.*?)<\/td><\/tr>/',$s,$mtc,PREG_SET_ORDER)) {
foreach($mtc as $v){
if($v[2] == '<i>no value</i>') continue;
$a[$v[1]] = $v[2];
}
}
return $a;
}

This is a slight modification to the previous code by "code at adspeed dot com" that extracts the PHP modules as an array. I used it on PHP 4.1.2 and it failed as the <h2> tags also had an align="center". So this update changes the regex for those tags:
<?php
/* parse php modules from phpinfo */
function parsePHPModules() {
ob_start();
phpinfo(INFO_MODULES);
$s = ob_get_contents();
ob_end_clean();
$s = strip_tags($s,'<h2><th><td>');
$s = preg_replace('/<th[^>]*>([^<]+)<\/th>/',"<info>\\1</info>",$s);
$s = preg_replace('/<td[^>]*>([^<]+)<\/td>/',"<info>\\1</info>",$s);
$vTmp = preg_split('/(<h2[^>]*>[^<]+<\/h2>)/',$s,-1,PREG_SPLIT_DELIM_CAPTURE);
$vModules = array();
for ($i=1;$i<count($vTmp);$i++) {
if (preg_match('/<h2[^>]*>([^<]+)<\/h2>/',$vTmp[$i],$vMat)) {
$vName = trim($vMat[1]);
$vTmp2 = explode("\n",$vTmp[$i+1]);
foreach ($vTmp2 AS $vOne) {
$vPat = '<info>([^<]+)<\/info>';
$vPat3 = "/$vPat\s*$vPat\s*$vPat/";
$vPat2 = "/$vPat\s*$vPat/";
if (preg_match($vPat3,$vOne,$vMat)) { // 3cols
$vModules[$vName][trim($vMat[1])] = array(trim($vMat[2]),trim($vMat[3]));
} elseif (preg_match($vPat2,$vOne,$vMat)) { // 2cols
$vModules[$vName][trim($vMat[1])] = trim($vMat[2]);
}
}
}
}
return $vModules;
}
?>

My hosting company doesn't let me edit my php.ini file, but I wanted most of the same values, so I adapted one of the above posts to let me convert the information from phpinfo into a page where so can just copy and paste the info into a new php.ini file.
<?php
ob_start();
phpinfo(INFO_CONFIGURATION);
$phpinfo = array('phpinfo' => array());
if(preg_match_all('#(?:<h2>(?:<a name=".*?">)?(.*?)(?:</a>)?</h2>)|(?:<tr(?: class=".*?")?><t[hd](?: class=".*?")?>(.*?)\s*</t[hd]>(?:<t[hd](?: class=".*?")?>(.*?)\s*</t[hd]>(?:<t[hd](?: class=".*?")?>(.*?)\s*</t[hd]>)?)?</tr>)#s', ob_get_clean(), $matches, PREG_SET_ORDER))
foreach($matches as $match)
if(strlen($match[1]))
$phpinfo[$match[1]] = array();
elseif(isset($match[3]))
$phpinfo[end(array_keys($phpinfo))][$match[2]] = isset($match[4]) ? array($match[3], $match[4]) : $match[3];
else
$phpinfo[end(array_keys($phpinfo))][] = $match[2];
?>
<?php
foreach($phpinfo as $name => $section) {
foreach($section as $key => $val) {
if(is_array($val))
echo "$key = $val[0]<br>";
elseif(is_string($key))
echo "$key = $val<br>";
else
echo "$val<br>";
}
echo "\n";
}
?>

To obtain a phpinfo without headers (and css) :
<?php
ob_start();
phpinfo();
$info = ob_get_contents();
ob_end_clean();
$info = preg_replace('%^.*<body>(.*)</body>.*$%ms', '$1', $info);
?>
You can then style your tables & headings :)

Here's a variant of "print it without headers, but include the style information":
<?php
ob_start();
phpinfo();
$info = ob_get_clean ();
$matches = array ();
$i = preg_match ('%(<style type="text/css">.*</style>).*<body>(.*)</body>%s', $info, $matches);
print $matches [1]; # Style information
print $matches [2]; # Body

I have been working extensively with portable Web Servers (i.e.: Uniform Server), and was trying to incorporate XSL, Tomcat and ASP. I decided first to 'modify' the way my php_info() appears, allowing a listing of currently loaded extensions. Hope someone finds this useful.
<?php
// Get PHP INFO
ob_start();
phpinfo();
$phpinfo = ob_get_contents();
ob_end_clean();
$phpinfo = preg_replace ('/<\/div><\/body><\/html>/', '', $phpinfo);
//HR
$hr = '<div style="width:100%;background:#000; height:10px;margin-bottom:1em;"></div>'.PHP_EOL;
//GET EXT INFO
ob_start();
echo '<table border="0" cellpadding="3" width="600">'.PHP_EOL;
echo '<tr class="h"><td><a href="http://www.php.net/">';
echo '<img border="0" src="http://static.php.net/www.php.net/images/php.gif" alt="PHP Logo" />';
echo '</a><h1 class="p">PHP Extensions</h1>'.PHP_EOL;
echo '</td></tr>'.PHP_EOL;
echo '</table><br />'.PHP_EOL;
echo '<h2>Overview</h2>'.PHP_EOL;
echo '<table border="0" cellpadding="3" width="600">'.PHP_EOL;
echo '<tr><td class="e">Extensions</td><td class="v">'.PHP_EOL;
$exts = array();
foreach (get_loaded_extensions() as $ext) {
$exts[] = $ext;
}
echo implode(', ', $exts).PHP_EOL;
echo '</td></tr></table><br />'.PHP_EOL;
echo '<h2>Details</h2>'.PHP_EOL;
echo '<table border="0" cellpadding="3" width="600">'.PHP_EOL;
foreach ($exts as $ext) {
echo '<tr><td class="e">'.$ext.'</td><td class="v">';
$funcs = array();
foreach (get_extension_funcs($ext) as $func) {
$funcs[] = $func;
}
echo implode(', ', $funcs).PHP_EOL;
echo '</td></tr>'.PHP_EOL;
}
echo '</table><br />'.PHP_EOL;
echo '</div></body></html>'.PHP_EOL;
$extinfo = ob_get_contents();
ob_end_clean();
//OUTPUT
echo $phpinfo.$hr.$extinfo;
?>
