Removing all punctuation

[drknow]

How would i go about removing all punctuation, special characters, slashes, html tags, ect. from a string???

Any help is greatly appreciated.

You'd use preg_replace, and feed it a regular expression describing what you want to delete. Replace the hits with nothing.

<?
$string = 'abcde66666;<>//who am i, [e-mail] ??';
$string = preg_replace('/[^a-zA-Z0-9 ]/','',$string);
echo $string;
?>

In this case, the regex says 'anything that is NOT in the sets a through z, A through Z, 0 through 9.'

Result is

abcde66666who am i foobarcom

ok, so i guess i can use ereg_replace to do the same thing, right?

What about html tag removal??

Yes, but preg_replace is faster and more versatile.

What about html tag removal??
