ini_get

(PHP 4 )

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-existant value, will return an empty string.

When querying boolean values: A boolean ini value of off will be returned as an empty string 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, NOT its integer equivalent. Attempting normal arithmetic functions on these values will not have otherwise expected results.

<?php
/*
Our php.ini contains the following settings:

display_errors = On
register_globals = Off
post_max_size = 8M
*/

print 'display_errors = ' . ini_get('display_errors') . "\n";
print 'register_globals = ' . ini_get('register_globals') . "\n";
print 'post_max_size = ' . ini_get('post_max_size') . "\n";
print 'post_max_size+1 = ' . (ini_get('post_max_size')+1) . "\n"; 

/*
This script will produce:

display_errors = 1
register_globals = 
post_max_size = 8M
post_max_size+1 = 9
*/
 ?>
