Just use the str_replace().
$chars = array('!', '@', '#');
echo str_replace($chars, '', 'oh! texto com # e @ para apagar!');
Behold working in the ideone. And in the repl it.. Also put on the Github for future reference.

Using the following regular expression:
[^\w]
And make the substitution using preg_replace:
$texto = 'Ex#em$!plo uti@!lizando r3gex';
echo preg_replace('/[^\w]/', '', $texto);

You can use several str_replace cascades by substituting "" (empty string). or regular expressions (never tested)
