                            mcrypt_list_algorithms

   (PHP 4 >= 4.0.2)
   mcrypt_list_algorithms -- Get an array of all supported ciphers

Description

   array mcrypt_list_algorithms ( [string lib_dir])

   mcrypt_list_algorithms() is used to get an array of all supported
   algorithms in the lib_dir parameter.

   mcrypt_list_algorithms() takes an optional lib_dir parameter which
   specifies the directory where all algorithms are located. If not
   specifies, the value of the mcrypt.algorithms_dir php.ini directive is
   used.

   Example 1. mcrypt_list_algorithms() Example
   <?php
       $algorithms = mcrypt_list_algorithms("/usr/local/lib/libmcrypt");
       foreach ($algorithms as $cipher) {
           echo "$cipher<br />\n";
       }
   ?>

   The above example will produce a list with all supported algorithms in
   the "/usr/local/lib/libmcrypt" directory.
