                                    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
   */
   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";
   ?>

   This script will produce:
display_errors = 1
register_globals = 0
post_max_size = 8M
post_max_size+1 = 9
