PHP Finding the position of a string in another string using strpos

$dot_location = strpos($my_string,".");


$my_string = "12345.";
$pos = strpos($my_string,".");
if ($pos === false) {
  // dot not found
} else {
  // dot found

This is my test area for webdev. I keep a collection of code snippits here, mostly for my reference. Also if i find a good site, i usually add it here.
