# 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-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
