[RESOLVED] preg_replace, help with pattern

[johanafm]

I need to grab text in between two tags, without a possible ending full stop, or if tags are not present, return no text at all.

The following should both return "Grab me":
(1) "text[tag]Grab me[/tag]text"
(2) "text[tag]Grab me.[/tag]text"

And this should return "":
(3) "text Grab me text"

Cases (1) and (2) work, while (3) returns: "text Grab me text".

function getTagText($str, $startTag, $endTag) {
	return preg_replace("/.*".$startTag."(.*?)".$endTag.".*/s", '$1', $str);
}

$str .= getTagText($article['body'], "\[tag\]", "\.?+\[\/tag\]");

So, why does it return everything in $article['body'] when there is no "[tag]"?

Any input appreciated
regards
johan

Brain on vacation... preg_replace is supposed to return the subject string when no match is found.
