Hi,

looks like you’re reading the output of the regex wrong. You want the array to return all occurrences of (THIS!), right?
But you’re getting one time match of the whole pattern.

If you do the following:
[php]
$allLinks = $output[1];
[/php]

you can step through the resultlist of of just the part between parentheses. ( it’s in $allLinks ).
For a more elaborate description of how preg_match_all() works, http://php.net/manual/en/function.preg-match-all.php 8)

I hope this helps.
Good luck.
