Re: [PHP] how do i remove the first 3 characters from a variable?

[Chris Lambert - WhiteCrown Networks]

To loop:
unset($temp);
$vars = array("this", "that");
foreach ($vars as $var) {
    $temp[] = substr($var, 0, 3);
}
$vars = $temp;

Single array element:
$vars = array("this", "that");
$vars[1] = substr($vars[1], 0, 3);
