parse_ini_file

(PHP 4, PHP 5, PHP 7)

parse_ini_fileParst eine Konfigurationsdatei

Beschreibung

parse_ini_file ( string $filename [, bool $process_sections = FALSE [, int $scanner_mode = INI_SCANNER_NORMAL ]] ) : array

parse_ini_file() lädt die in filename angegebene Datei, und gibt die darin enthaltenen Einstellungen in einem assoziativen Array zurück.

Die Struktur der Ini-Datei ist identisch zur php.ini.

Parameter-Liste

filename

Der Dateiname der zu ladenden ini-Datei.

process_sections

Setzt man den Parameter process_sections auf TRUE, erhält man ein mehrdimensionales Array mit den Gruppennamen und Einstellungen. Der Standardwert für process_sections ist FALSE

scanner_mode

Kann entweder INI_SCANNER_NORMAL (Standard) oder INI_SCANNER_RAW sein. Ist INI_SCANNER_RAW gesetzt, so werden die Werte der Optionen nicht geparst.

Seit PHP 5.6.1 kann auch INI_SCANNER_TYPED angegeben werden. In diesem Modus werden soweit möglich die Typen von Boolean-, Null- oder Integer-Werten beibehalten. Die Zeichenketten "true", "on" und "yes" werden zu TRUE konvertiert. "false", "off", "no" und "none" werden als FALSE angesehen. "null" wird in diesem Modus zu NULL. Soweit möglich werden alle numerischen Zeichenketten zu Integertypen umgewandelt.

Rückgabewerte

Im Erfolgsfall werden die Einstellungen als assoziatives Array zurückgegeben, ansonsten FALSE.

Changelog

Version Beschreibung
7.0.0 Das Raute-Symbol (#) kann nicht mehr für Kommentare verwendet werden.
5.6.1 Neuen Modus INI_SCANNER_TYPED hinzugefügt.
5.3.0 Der optionale Parameter scanner_mode wurde hinzugefügt. Einfache Anführungszeichen können nun um Variablenzuordnungen herum verwendet werden. Rautezeichen (# können nicht länger für Kommentare verwendet werden und bei Verwendung wird eine Warnung zur veralteten Benutzung ausgegeben.
5.2.7 Bei einem Syntaxfehler gibt die Funktion nun FALSE statt eines leeren Array zurück.
5.2.4 Schlüssel und Gruppennamen mit Ziffern werden nun als Integer von PHP ausgewertet, weshalb Zahlen, die mit einer 0 beginnen, als Oktalzahlen und Zahlen, die mit 0x beginnen, als Hexadezimalzahlen verstanden werden.

Beispiele

Beispiel #1 Inhalt der sample.ini

; Dies ist ein Beispiel für eine Konfigurationsdatei
; Kommentare beginnen wie in der php.ini mit ';'

[erste_gruppe]
eins = 1
fünf = 5
tier = VOGEL

[zweite_gruppe]
pfad = /usr/local/bin
URL = "http://www.example.com/~username"

[dritte_gruppe]
phpversion[] = "5.0"
phpversion[] = "5.1"
phpversion[] = "5.2"
phpversion[] = "5.3"

urls[svn] = "http://svn.php.net"
urls[git] = "http://git.php.net"

Beispiel #2 parse_ini_file()-Beispiel

Konstanten in einer Ini-Datei können ebenfalls geparst werden indem man eine Konstante als INI-Wert definiert, bevor parse_ini_file() aufgerufen wird. Dieser Wert wird in die Ergebnisse integriert, dabei werden nur INI-Werte ausgewertet. Zum Beispiel:

<?php

define 
('VOGEL''Amsel');

// Ohne Gruppen analysieren
$ini_array parse_ini_file("sample.ini");
print_r($ini_array);

// Mit Gruppen analysieren
$ini_array parse_ini_file("sample.ini"TRUE);
print_r($ini_array);

?>

Das oben gezeigte Beispiel erzeugt eine ähnliche Ausgabe wie:

(
    [eins] => 1
    [fünf] => 5
    [tier] => Amsel
    [pfad] => /usr/local/bin

Beispiel #3 parse_ini_file() parst eine php.ini

<?php
    
// Eine einfache Funktion, um das Ergebnis zu vergleichen
    
function janein($expression)
    {
        return(
$expression 'Ja' 'Nein');
    }

    
// Pfad der php.ini mittels der Funktion php_ini_loaded_file()
    // holen, die seit PHP 5.2.4 verfügbar ist
    
$ini_path php_ini_loaded_file();

    
// Parsen der php.ini
    
$ini parse_ini_file($ini_path);

    
// Werte ausgeben und vergleichen. Beachten Sie dass die Verwendung von
    // get_cfg_var() die gleichen Ergebnisse für geparste und geladene
    // Werte geben wird
    
echo '(geparst) magic_quotes_gpc = ' janein($ini['magic_quotes_gpc']) . PHP_EOL;
    echo 
'(geladen) magic_quotes_gpc = ' janein(get_cfg_var('magic_quotes_gpc')) . PHP_EOL;
    
?>

Das oben gezeigte Beispiel erzeugt eine ähnliche Ausgabe wie:

    (geparst) magic_quotes_gpc = Ja
    (geladen) magic_quotes_gpc = Nein
    

Anmerkungen

Hinweis:

Diese Funktion hat nichts mit dem Laden der php.ini-Datei zu tun. Diese ist zum Ausführungszeitpunkt Ihres Skriptes bereits vollständig verarbeitet. Diese Funktion kann verwendet werden, um die Konfigurationsdateien Ihrer eigenen Anwendung zu lesen.

Hinweis:

Falls ein Wert der Ini-Datei ein nicht alphanumerisches Zeichen enthält muss dieser Wert in doppelte Anführungszeichen (") eingeschlossen werden.

Hinweis: Es gibt reservierte Schlüsselwörter, welche nicht als Schlüssel in Ini-Dateien verwendet werden dürfen. Diese umfassen: null, yes, no, true, false, on, off, none. Die Werte null, off, no und false ergeben "" und die Werte on, yes and true ergeben "1", solange der Modus INI_SCANNER_TYPED nicht verwendet wird (seit PHP 5.6.1). Die Zeichen ?{}|&~!()^" dürfen in einem Schlüssel nicht verwendet werden und haben im Wert besondere Bedeutung.

Hinweis:

Einträge ohne Gleichheitszeichen werden ignoriert. Beispielsweise würde "foo" ignoriert werden, während "bar =" geparst und mit einem leeren Wert hinzugefügt würde. Beispielsweise hat MySQL eine Einstellung "no-auto-rehash" in der my.cnf welche keinen Wert enthält und somit ignoriert würde.

Here is a quick parse_ini_file wrapper to add extend support to save typing and redundancy.
<?php
   
/**
     * Parses INI file adding extends functionality via ":base" postfix on namespace.
     *
     * @param string $filename
     * @return array
     */
   
function parse_ini_file_extended($filename) {
       
$p_ini = parse_ini_file($filename, true);
       
$config = array();
        foreach(
$p_ini as $namespace => $properties){
            list(
$name, $extends) = explode(':', $namespace);
           
$name = trim($name);
           
$extends = trim($extends);
           
// create namespace if necessary
           
if(!isset($config[$name])) $config[$name] = array();
           
// inherit base namespace
           
if(isset($p_ini[$extends])){
                foreach(
$p_ini[$extends] as $prop => $val)
                   
$config[$name][$prop] = $val;
            }
           
// overwrite / set current namespace values
           
foreach($properties as $prop => $val)
           
$config[$name][$prop] = $val;
        }
        return
$config;
    }
?>

Treats this ini:
<?php
/*
[base]
host=localhost
user=testuser
pass=testpass
database=default

[users:base]
database=users

[archive : base]
database=archive
*/
?>
As if it were like this:
<?php
/*
[base]
host=localhost
user=testuser
pass=testpass
database=default

[users:base]
host=localhost
user=testuser
pass=testpass
database=users

[archive : base]
host=localhost
user=testuser
pass=testpass
database=archive
*/

You may want, in some very special cases, to parse multi-dimensional array with N levels in your ini file. Something like setting[data][config][debug] = true will result in an error (expected "=").

Here's a little function to match this, using dots (customizable).
<?php
function parse_ini_file_multi($file, $process_sections = false, $scanner_mode = INI_SCANNER_NORMAL) {
   
$explode_str = '.';
   
$escape_char = "'";
   
// load ini file the normal way
   
$data = parse_ini_file($file, $process_sections, $scanner_mode);
    if (!
$process_sections) {
       
$data = array($data);
    }
    foreach (
$data as $section_key => $section) {
       
// loop inside the section
       
foreach ($section as $key => $value) {
            if (
strpos($key, $explode_str)) {
                if (
substr($key, 0, 1) !== $escape_char) {
                   
// key has a dot. Explode on it, then parse each subkeys
                    // and set value at the right place thanks to references
                   
$sub_keys = explode($explode_str, $key);
                   
$subs =& $data[$section_key];
                    foreach (
$sub_keys as $sub_key) {
                        if (!isset(
$subs[$sub_key])) {
                           
$subs[$sub_key] = [];
                        }
                       
$subs =& $subs[$sub_key];
                    }
                   
// set the value at the right place
                   
$subs = $value;
                   
// unset the dotted key, we don't need it anymore
                   
unset($data[$section_key][$key]);
                }
               
// we have escaped the key, so we keep dots as they are
               
else {
                   
$new_key = trim($key, $escape_char);
                   
$data[$section_key][$new_key] = $value;
                    unset(
$data[$section_key][$key]);
                }
            }
        }
    }
    if (!
$process_sections) {
       
$data = $data[0];
    }
    return
$data;
}
?>

The following file:
<?php
/*
[normal]
foo = bar
; use quotes to keep your key as it is
'foo.with.dots' = true

[array]
foo[] = 1
foo[] = 2

[dictionary]
foo[debug] = false
foo[path] = /some/path

[multi]
foo.data.config.debug = true
foo.data.password = 123456
*/
?>

will result in:
<?php
parse_ini_file_multi
('file.ini', true);

Array
(
    [
normal] => Array
        (
            [
foo] => bar
           
[foo.with.dots] => 1
       
)
    [array] => Array
        (
            [
foo] => Array
                (
                    [
0] => 1
                   
[1] => 2
               
)
        )
    [
dictionary] => Array
        (
            [
foo] => Array
                (
                    [
debug] =>
                    [
path] => /some/path
               
)
        )
    [
multi] => Array
        (
            [
foo] => Array
                (
                    [
data] => Array
                        (
                            [
config] => Array
                                (
                                    [
debug] => 1
                               
)
                            [
password] => 123456
                       
)
                )

.ini files or JSON file format as it is also known as, are very useful format to store stuff in. Especially large arrays.

Strangely enough there is this nice function to read the file, but no function to write it.

So here is one.

Use it as:  put_ini_file(string $file, array $array)

<?php
function put_ini_file($file, $array, $i = 0){
 
$str="";
  foreach (
$array as $k => $v){
    if (
is_array($v)){
     
$str.=str_repeat(" ",$i*2)."[$k]".PHP_EOL;
     
$str.=put_ini_file("",$v, $i+1);
    }else
     
$str.=str_repeat(" ",$i*2)."$k = $v".PHP_EOL;
  }
if(
$file)
    return
file_put_contents($file,$str);
  else
    return
$str;
}
?>

This is a simple (but slightly hackish) way of avoiding the character limitations (in values):

<?php
define
('QUOTE', '"');
$test = parse_ini_file('test.ini');

echo
"<pre>";
print_r($test);
?>

contents of test.ini:

park yesterday = "I (walked) | {to} " QUOTE"the"QUOTE " park yesterday & saw ~three~ dogs!"

output:

<?php
Array
(
    [
park yesterday] => I (walked) | {to} "the" park yesterday & saw ~three~ dogs!
)
?>

The documentation states:
Characters ?{}|&~!()^" must not be used anywhere in the key and have a special meaning in the value.

Here's the results of my experiments on what they mean:

; | is used for bitwise OR
three = 2|3

; & is used for bitwise AND
four = 6&5

; ^ is used for bitwise XOR
five = 3^6

; ~ is used for bitwise negate
negative_two = ~1

; () is used for grouping
seven = (8|7)&(6|5)

; ${...} is used for grabbing values from the environment, or previously defined values.
path = ${PATH}
also = ${five}

; ? I have no guess for
; ! I have no guess for

Looks like in PHP 5.3.0 special characters like \n are extrapolated into real newlines. Gotta use \\n.

Just a quick note for all those running into trouble escaping double quotes:

I got around this by "base64_encode()"-ing my content on the way in to the ini file, and "base64_decode()"-ing on the way out.

Because base64 uses the "=" sign, you will have to encapsulate the entire value in double quotes so the line looks like this:

    varname = "TmlhZ2FyYSBGYWxscywgT04="

When base64'd, your strings will retain all \n, \t...etc...  URL's retain everything perfectly :-)

I hope some of you find this useful!

Cheers, Kieran

Warning: parse_ini_files cannot cope with values containing the equal sign (=).

The following function supports sections, comments, arrays, and key-value pairs outside of any section.
Beware that similar keys will overwrite one another (unless in different sections).

<?php
function parse_ini ( $filepath ) {
   
$ini = file( $filepath );
    if (
count( $ini ) == 0 ) { return array(); }
   
$sections = array();
   
$values = array();
   
$globals = array();
   
$i = 0;
    foreach(
$ini as $line ){
       
$line = trim( $line );
       
// Comments
       
if ( $line == '' || $line{0} == ';' ) { continue; }
       
// Sections
       
if ( $line{0} == '[' ) {
           
$sections[] = substr( $line, 1, -1 );
           
$i++;
            continue;
        }
       
// Key-value pair
       
list( $key, $value ) = explode( '=', $line, 2 );
       
$key = trim( $key );
       
$value = trim( $value );
        if (
$i == 0 ) {
           
// Array values
           
if ( substr( $line, -1, 2 ) == '[]' ) {
               
$globals[ $key ][] = $value;
            } else {
               
$globals[ $key ] = $value;
            }
        } else {
           
// Array values
           
if ( substr( $line, -1, 2 ) == '[]' ) {
               
$values[ $i - 1 ][ $key ][] = $value;
            } else {
               
$values[ $i - 1 ][ $key ] = $value;
            }
        }
    }
    for(
$j=0; $j<$i; $j++ ) {
       
$result[ $sections[ $j ] ] = $values[ $j ];
    }
    return
$result + $globals;
}
?>

Example usage:
<?php
$stores
= parse_ini('stores.ini');
print_r( $stores );
?>

An example ini file:
<?php
/*
;Commented line start with ';'
global_value1 = a string value
global_value1 = another string value

; empty lines are discarded
[Section1]
key = value
; whitespace around keys and values is discarded too
otherkey=other value
otherkey=yet another value
; this key-value pair will overwrite the former.
*/

Not mentioned in the documentation, this function acts like include:

"Files are included based on the file path given or, if none is given, the include_path specified. If the file isn't found in the include_path, include will finally check in the calling script's own directory and the current working directory before failing."

(At least for PHP 7; have not checked PHP 5.)

This core function won't handle ini key[][] = value(s), (multidimensional arrays), so if you need to support that kind of setup you will need to write your own function. one way to do it is to convert all the key = value(s) to array string [key][][]=value(s), then use parse_str() to convert all those [key][][]=value(s) that way you just read the ini file line by line, instead of doing crazy foreach() loops to handle those (multidimensional arrays) in each section, example...

ini file...... config.php

<?php

; This is a sample configuration file
; Comments start with ';', as in php.ini

[first_section]
one = 1
five

animal
= BIRD

[second_section]
path = "/usr/local/bin"
URL = "http://www.example.com/~username"

[third_section]
phpversion[] = "5.0"
phpversion[] = "5.1"
phpversion[] = "5.2"
phpversion[] = "5.3"

urls[svn] = "http://svn.php.net"
urls[git] = "http://git.php.net"

[fourth_section]

a[][][] = b
a
[][][][] = c
a
[test_test][][] = d
test
[one][two][three] = true

?>

echo parse_ini_file ( "C:\\services\\www\\docs\\config.php" );

results in...

Class to access ini values at format "section_name.property", for example $myconf->get("system.name") returns a property "name" in section "system":

<?php
class Settings {

var
$properties = array();

    function
Settings() {
       
$this->properties = parse_ini_file(_SETTINGS_FILE, true);
    }

    function
get($name) {
        if(
strpos($name, ".")) {
            list(
$section_name, $property) = explode(".", $name);
           
$section =& $this->properties[$section_name];
           
$name = $property;
        } else {
           
$section =& $properties;
        }

        if(
is_array($section) && isset($section[$name])) {
            return
$section[$name];
        }
        return
false;
    }

}
?>

I found that this function will not work on remote files.
I tried

$someArray = parse_ini_file("http://www.example.com/setting.ini");

and it reports

Cannot Open 'http://www.example.com/setting.ini' for reading ...

parse_ini_file can't deal with const which cancate a string. For example, if test.ini file is

classPath = ROOT/lib

If you:
<?php
define
('ROOT', dirname(__FILE__));

$buf = parse_ini_file('test.ini');
?>

const ROOT would't be parsed.

But my version could work find.

<?php
// array parse_ini_file ( string $filename [, bool $process_sections] )
function parse_ini($filename, $process_sections = false)
{
  function
replace_process(& $item, $key, $consts)
  {
   
$item = str_replace(array_keys($consts), array_values($consts), $item);
  }

 
$buf = get_defined_constants(true); // PHP version > 5.0
 
$consts = $buf['user'];
 
$ini = parse_ini_file($filename, $process_sections);

 
array_walk_recursive($ini, 'replace_process', $consts);
  return
$ini;
}

define('ROOT', '/test');
print_r(parse_ini(dirname(__FILE__).'/test.ini'));

The parse_ini_file function does have trouble loading valid Windows ini files like, for example, nternet shortcuts (.url files).

This is due to the function reading the URLs as a value, and failing when it finds that valid URL characters like '=' appear unescaped or the value unquoted as a whole. Since Windows does not escape them anyway, the solution is to scan it in raw mode, where it will read unparsed the value after the first '='. Since = only appears in URLs with parameters, this mistake may is not be obvious at a first glance.

An example

<?php

$links
= array();

// ...

$files = scandir($directory);
foreach(
$files as $filename )
{
    if (
strToLower(pathinfo($filename, PATHINFO_EXTENSION)) === 'url')
    {
       
$shortcut = parse_ini_file( $directory.DIRECTORY_SEPARATOR.$filename, trueINI_SCANNER_RAW);
        if (
$shortcut === false) die('Syntax Error');
       
$url = $shortcut['InternetShortcut']['URL'];
       
$links []= $url;
    }
}

?>
