Question

The code should allow this to create variable $Dots
If the URL was for example:
http://example.com/1/2
It will result with a 1 and $Dots will contain ../ allowing all links/photos to show up easily. If it was to result in 2 it would return ../../ and so on. Though, it just infinitely loops.

<?php
        //Set up URL Dots. Fixes directory issues.
    $ORIGINAL_DOTS = str_ireplace('/test_link','',$_SERVER['REQUEST_URI']);
    $COUNT_DOTS = substr_count($ORIGINAL_DOTS,'/')-1;
    $END_DOTS = 0;
    $Dots = '';
    echo $COUNT_DOTS;
    if($COUNT_DOTS != 0){
        while ($END_DOTS <= $COUNT_DOTS){
            if($END_DOTS != $COUNT_DOTS){
                $END_DOTS ++;
                $Dots .= '../';
            }
        }
    }
?>

Yes, your loop will run forever.

while ($END_DOTS <= $COUNT_DOTS){
  if($END_DOTS != $COUNT_DOTS){
    $END_DOTS ++;
    $Dots .= '../';
  }
}

Consider what will happen when $END_DOTS == $COUNT_DOTS. The if-block within the loop won’t execute, so the condition $END_DOTS <= $COUNT_DOTS will remain true, hence the loop will run forever.

Instead, you should use

while ($END_DOTS < $COUNT_DOTS){
  $END_DOTS ++;
  $Dots .= '../';
}
