oops....
foreach($array as $key=>$val) {
$array[$key] = substr($val, 3);
}
this is cleaner.

Subject: RE: [PHP] how do i remove the first 3 characters from a
variable?
I think your question was answered already by Chris,
if not (or if you think two examples are better then one) then:
$array[0] = 'how do i remove the first 3 characters from a variable?';
$array[1] = 'when do i remove the first 3 characters from a variable?';
$array[2] = 'why do i remove the first 3 characters from a variable?';
foreach($array as $key=>$val) {
$array[$key] = substr($array[$key], 3);
}
this will produce:
$array[0] = ' do i remove the first 3 characters from a variable?';
$array[1] = 'n do i remove the first 3 characters from a variable?';
$array[2] = ' do i remove the first 3 characters from a variable?';

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);
