ini_get
(PHP 4)
Description
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 .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 */?
