Strip excessed characters

[AnhTuanCool]

Hi all,
I'm looking for a PHP function that can strip off excessed characters. Like I limited $mystring is only 10 characters and if someone enter the value for $mystring over 10 characters, then those excessed characters will be stripped.
Any help would be much appreciated. :)

You can either make the corresponding database column VARCHAR(10) or use:

$s = substr($s, 0, 10);
