Your function doesn't quite work as expected. If you want to insert something, say 20
characters from the end it works, but not 20 characters from the beginning.
Slight tweak:
function insert_substr($str, $pos, $substr) {
$pos = strlen($str) - $pos;
$part1 = substr($str, 0, -$pos);
$part2 = substr($str, -$pos);
return $part1.$substr.$part2;
}
$str = "12345678901234567890123456789";
echo insert_substr($str, 20, "<br />");
Output: "12345678901234567890<br />123456789"
