Parse out the first n chars of a string

[Anon]

How would i go about selecting say the first 50 characters in a string variable. I have tried (without luck) ereg("(.{0,50}).,$string,$arr). and using $arr[1]. any help? thanks.

I guess you mean $arr[0] instead of $arr[1]. A better way should be this:

function GetNChars($n, $str) {
   $str = substr($str, 0, $n);
   return $str;
}
