    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.

    Parameters

    varname

    The configuration option name.

    Return Values

    Returns the value of the configuration option as a string on success, or an empty string on failure or for null values.

    Examples

    Example #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;
    }

    ?>

    The above example will output something similar to:

    
    display_errors = 1
    register_globals = 0
    post_max_size = 8M
    post_max_size+1 = 9
    post_max_size in bytes = 8388608
    
    

    Notes

    Note: 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". The function can also return the literal string of INI value.

    Note: 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 above shows one way to convert shorthand notation into bytes, much like how the PHP source does it.
