mcrypt_list_modes -- Get an array of all supported modes

Description

array mcrypt_list_modes ( [string lib_dir] )

mcrypt_list_modes() is used to get an array of all supported modes in the lib_dir .

mcrypt_list_modes() takes as optional parameter a directory which specifies the directory where all modes are located. If not specifies, the value of the mcrypt.modes_dir php.ini directive is used.

Example 1. mcrypt_list_modes() Example

<?php
    $modes = mcrypt_list_modes();

    foreach ($modes as $mode) {
        echo "$mode <br />\n";
    }
?>

The above example will produce a list with all supported algorithms in the default mode directory. If it is not set with the ini directive mcrypt.modes_dir, the default directory of mcrypt is used (which is /usr/local/lib/libmcrypt).
