PHP strpos( ) - function problem.

Hi, I have made myself a shortlist feature which collects id's and stores them in a session's variable. I then use the strpos( ) function to check if the id is in the variable and change a button class from 'Add to Shortlist' to 'Added'

However, I have a place with an id of 3 and a place with an id of 13. When I add the place with an id of 13 to my shortlist and then go to my place with an id of 3 it believes it's in the shortlist and the number 3 is present in 13.

Is there a way to change alter the function so it takes the absolute value rather than just single integers?

Thanks

Why aren't you just checking the id against the session variable with an if statement?

This is true.. Maybe a slightly easier method would be to say (this is in note form):

<?php
// When you're checking what the button content should be: (Added/Add to shortlist)

place_id = 5;
foreach($_GET as $id) {
  if ($place_id == $id) {
 // I think you will have to use == instead of === because all $_GET params are strings
// you would be comparing string and int.
    $button_text = 'abc';
  } else {
    $button_text = 'def';
  }
}
