ini_get

(PHP 4, PHP 5)ini_get -- Gets the value of a configuration option

Description

string ini_get (string varname)

Returns the value of the configuration option on success. Failure, such as querying for a non-existent value, will return an empty string.

When querying boolean values: A boolean ini value of off will be returned as an empty string or "0" while a boolean ini value of on will be returned as "1".

When querying memory size values: Many ini memory size values, such as upload_max_filesize, are stored in the php.ini file in shorthand notation. ini_get() will return the exact string stored in the php.ini file and NOT its integer equivalent. Attempting normal arithmetic functions on these values will not have otherwise expected results. The example below shows one way to convert shorthand notation into bytes, much like how the PHP source does it.

Пример 1. A few ini_get() examples

<?php

/*

Our php.ini contains the following settings:

display_errors = On

register_globals = Off

post_max_size = 8M

*/

echo 'display_errors = ' . ini_get('display_errors') . "\n";

echo 'register_globals = ' . ini_get('register_globals') . "\n";

echo 'post_max_size = ' . ini_get('post_max_size') . "\n";

echo 'post_max_size+1 = ' . (ini_get('post_max_size')+1) . "\n";

echo 'post_max_size in bytes = ' . return_bytes(ini_get('post_max_size'));

function return_bytes($val){

$val = trim($val);

$last = strtolower($val{strlen($val)-1});

switch($last){

// The 'G' modifier is available since PHP 5.1.0

case 'g':

$val *= 1024;

case 'm':

$val *= 1024;

case 'k':

$val *= 1024;

}

return $val;

}

?>

This script will produce: 

display_errors = 1

register_globals = 0

post_max_size = 8M

post_max_size+1 = 9

post_max_size in bytes = 8388608
