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.
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 poichè 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.

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();

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.

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
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;
}

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

same as above for configuration variables
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;
}
?>

To obtain a phpinfo without headers (and css) :
<?
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 :)

This function parses the phpinfo output to get details about a PHP module.
/** 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
[WBMP Support] => enabled

[Timezone Database Version] => 2005.14
[Timezone Database] => internal
[Default timezone] => America/Los_Angeles
[Directive] => Array (
[0] => Local Value
[1] => Master Value
)
[date.timezone] => Array (
[0] => no value
[1] => no value
)
)
/** 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)"

check out this cool and fantastic colourful phpinfo()!
<?php
ob_start();
phpinfo();
$phpinfo = ob_get_contents();
ob_end_clean();
preg_match_all('/#[0-9a-fA-F]{6}/', $phpinfo, $rawmatches);
for ($i = 0; $i < count($rawmatches[0]); $i++)
$matches[] = $rawmatches[0][$i];
$matches = array_unique($matches);
$hexvalue = '0123456789abcdef';
$j = 0;
foreach ($matches as $match)
{
$r = '#';
$searches[$j] = $match;
for ($i = 0; $i < 6; $i++)
$r .= substr($hexvalue, mt_rand(0, 15), 1);
$replacements[$j++] = $r;
unset($r);
}
for ($i = 0; $i < count($searches); $i++)
$phpinfo = str_replace($searches, $replacements, $phpinfo);
echo $phpinfo;
?>
