<?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).
