Hi Pablo,
At a (reasonable) guess, I'd say it's because you're not using the "s"
pattern modifier in your preg_match_all()? The "s" modifier forces your
regular expression to match new lines with the "." metacharacter.
Try:
preg_match_all("/<!-- START PRINT -->(.*?)<!-- END PRINT -->/s", $str,
$out);

Hope this helps.
Much warmth,
Murray
