mcrypt_list_modes

Description

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>"; } ?>

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).
