But how can I use preg_match() to clear out all the unwanted characters using regular expressions? For example, if I used:

PHP Code:


			
<?php
$string = "!@#$abc";
echo preg_match("/^abc/", $string);
?>

That will output "abc", but what happens if I have for example "a!@#b!@#c", and try to use that same pattern? It wouldn't show any matches. So how could I do it using just preg_match?
