Warning

This function has been DEPRECATED as of PHP 7.1.0. Relying on this function is highly discouraged.

Description

array mcrypt_list_modes ([ string $lib_dir = ini_get("mcrypt.modes_dir") ] )

Gets the list of all supported modes in the lib_dir parameter.

Parameters

lib_dir

Specifies the directory where all modes are located. If not specified, the value of the mcrypt.modes_dir php.ini directive is used.

Return Values

Returns an array with all the supported modes.

Examples

Example #1 mcrypt_list_modes() Example

<?php
    $modes = mcrypt_list_modes();

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

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