Translating PHP mcrypt to exec

[laredotornado]

Hello, My hosting company does not support the PHP mcrypt functions.
Instead, they recomend using the command line, /usr/local/bin/mcrypt
utility via PHP's exec method. Sadly, they do not provide any
documentation how to do this. How would i translate the following

function encryptString($ p_str)
{
$iv_size = mcrypt_get_iv_s ize(MCRYPT_XTEA ,
MCRYPT_MODE_ECB );
$iv = mcrypt_create_i v($iv_size, MCRYPT_RAND);

$enc = mcrypt_encrypt( MCRYPT_XTEA,
ENCRYPTION_KEY, $p_str, MCRYPT_MODE_ECB , $iv);
return $enc;
} // encryptstring
to run via an exec command, returning the encrypted output to some PHP
variable?

I'm using PHP 4 on Linux if that's useful. Thanks, - Dave

You can usually find the man pages for UNIX stuff by via Google by
searching for the name and the word "man".
