why preg_match_all does not return the number of matches


Posted on 16th Feb 2014 07:03 pm by admin

My regex looks like

X[^x{4e00}-x{9fa5}]*Y

Did you know?Explore Trending and Topic pages for more stories like this.
(where X and Y are two Chinese characters)

and my expression looks like

preg_match_all("/".$regex."/iu", $content, $out, PREG_PATTERN_ORDER)

it turns out that preg_match_all is always returning 1, even though count($out[0]) is > 1 (and correctly so). So I ended up using count($out[0]) rather than the value this function returns. Though this solves the current issue I need, I am very curious why this is happening. Am I misunderstanding preg_match_all?

I'd greatly appreciate if anyone can point me to the explanation of this problem. Thanks in advance!
