Remove all characters except letters and numbers from a string
If you want to strip a string of all symbols and characters other than alphanumeric letters and numbers then use this. It will take a string and erase / delete any non-alphanumeric characters, and then output a clean version without the unwanted characters.
$string = "This is some text and numbers 12345 and symbols !£$%^&";
$new_string = ereg_replace("[^A-Za-z0-9]", "", $string);
