Test script: --------------- preg_match_all("/abba/", "abbabba", $resultats); foreach($resultats[0] as $resultat){ echo $resultat; } Expected result: ---------------- I expect to get 2x abba found instead of 1. I see 1x abba found. It is specifically said that it will be 1 because it start the second search after the end of the last result found. Why do it this way? It is not that hard to start after the first character of the string found. So There must be some kind of performance reason, which I would like to understand. This comes from the fact that I want to get ALL words in a sentence. But all words are surrounded by white spaces. So I have to put the white spaces in my regex. But because of that I HAVE to double the white spaces to get ALL words. Which is something I would like to avoid for performance. Please if you have time, send me an email to explain me why is it done that way. Thank you in advance. Actual result: -------------- I see 1x abba found. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/bug.php?id=53951&edit=1
