Bug #44999 [Com]: 0 equals any string

Edit report at https://bugs.php.net/bug.php?id=44999&edit=1 ID: 44999 Comment by: eric dot alex dot dube at gmail dot com Reported by: ethan dot nelson at ltd dot org Summary: 0 equals any string Status: Not a bug Type: Bug Package: Scripting Engine problem Operating System: windows 2003 PHP Version: 5.2.6 Block user comment: N Private report: N New Comment: It seems object do behave the way one would expect strings to (furthering the inconsistency imo), as demonstrated by this example: class Tester { } $tester = new Tester(); var_dump(0 == $tester); // false echo "<br />"; var_dump(0 == false); // true echo "<br />"; var_dump(false == $tester); // false echo "<br />"; Previous Comments: ------------------------------------------------------------------------ [2013-09-15 03:58:53] eric dot alex dot dube at gmail dot com I see this as the biggest inconsistency: var_dump(0 == "uno"); // true var_dump(0 == false); // true var_dump(false == "uno"); // false While perhaps not a bug by strict definition, I think it's definitely an error in design. ------------------------------------------------------------------------ [2013-04-21 21:44:35] contact at caus909 dot net Maybe because that's not a bug... "It's not a bug, it's a feature". Equality (==) and identity (===) are different, if for your use, equality is the best, just use it then. ------------------------------------------------------------------------ [2013-02-14 16:49:14] radamanf at gmail dot com I can see that it's no any logical explanation to keep this BUG unfixed! Status: Not a bug -> why??? It's not funny, so many years past. I do love to use PHP and like that no needed to define variable types, but this is generic FAIL. Come one guys, someone need to fix this, please. My PHP version PHP 5.3.10-1ubuntu3.5 with Suhosin-Patch (cli) (built: Jan 18 2013 23:45:59) ------------------------------------------------------------------------ [2012-08-24 08:16:07] bugs dot php dot net at simoneast dot net This is quite ridiculous. Can this 'feature' of PHP *please* be reconsidered? ------------------------------------------------------------------------ [2008-05-14 22:25:51] ethan dot nelson at ltd dot org I don't recall PHP ever behaving that way. So how do you alter a switch statement to use the identical operator instead of equivalency? It seems somewhat odd that any text character would be equvalent to integer 0. As I remember the chart it was something like: 0 == '0' true 0 == '' true 0 == null true 0 == false true 0 == 'text' false Basically if we are going to treat any string as equivalent to 0, the switch statement becomes useless when iterating through arrays unless you first strip key names of integer 0. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
