Hello guys :-) I have a question. I have been using str_replace() quite a lot of times, and never encountered any issue. But this time, something weird happened, and I am wondering wether, in fact, I have never really understood how this function worked, or if there is some kind of bug. If I do that : <?php $test = 'bla'; $un = array ('b', 'l', 'a'); $deux = array ('c', 'd', 'e'); $test = str_replace ($un, $deux, $test); echo $test , '<br />'; ?> No prob, the output is the one I would have expected : cde But if I do that : <?php $texte = 'cd' ; $original = array('a', 'b', 'c', 'd', 'e', 'f', 'g'); $modif = array ('c', 'd', 'e', 'f', 'g', 'h', 'i'); $texte = str_replace($original, $modif, $texte) ; echo $texte, ' <br />' ; ?> The result is : ih Why ? It seems to me that str_replace is messing up a litlle bit if there are identical values in both replacement and search arrays. Or am I missing something ? Thanks a lot :-) Johan
