Allowing only letters, numbers, spaces

[jackohara]

I know there is a function, I think its preg_replace(); that will remove all things other than letters, number, spaces (It may be ereg_replace()😉 could someone please write a code to show me how to do this.

Thanks

Yep, preg_replace(), like this:

<?PHP

$text = "This is a test.";
$newtext = preg_replace("/[^A-Za-z0-9 ]/", "", $text);
echo $newtext;
?>

Does this do spaces too? and thank you.

[pyro]

Yes it will. The above will print "This is a test" (no period)

The space is included in the function:

$newtext = preg_replace("/[^A-Za-z0-9 ]/", "", $text);
                          right here ^
