mcrypt_list_modes — Gets an array of all supported modes
This function has been DEPRECATED as of PHP 7.1.0 and REMOVED as of PHP 7.2.0. Relying on this function is highly discouraged.
   Gets the list of all supported modes in the
   lib_dir parameter.
  
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.
      
Returns an array with all the supported modes.
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).
