note 18288 added to function.array-search

> $map = array( 'version' => 4 > , 'OS' => 'Linux' > , 'lang' => 'english' > , 'short_tags' => true > ); > $key = array_search("4",$map); > print $key; > //returns short_tags > //strange results.. That's true, because when you're comparing the string "4" to the boolean value true, the string is transparently cast to a boolean. So in this case, "4" matches two of the elements of the array. When that happens, it seems that this function always returns the "last" one that matches, i.e. the one that was added to the array last. If you instead do $key = array_search("4",$map,true); then you still get a false return value, because the string "4" doesn't match the boolean or the integer in the array. But if you do $key = array_search(4,$map,true); then it works as expected. Note the lack of quotes on the 4, and note that you still need the optional third parameter ("strict") here. -- http://www.php.net/manual/en/function.array-search.php http://master.php.net/manage/user-notes.php?action=edit+18288 http://master.php.net/manage/user-notes.php?action=delete+18288 http://master.php.net/manage/user-notes.php?action=reject+18288
