<?php  
$ciphers = openssl_get_cipher_methods();  
$ciphers_and_aliases = openssl_get_cipher_methods(true);  
$cipher_aliases = array_diff($ciphers_and_aliases, $ciphers);  
print_r($ciphers);  
print_r($cipher_aliases);  
?>

The above example will output something similar to:

$ /usr/bin/php get_cipher_methods.php
