#35995 [Asn->Bgs]: Problems defining vars in arguments

ID: 35995 Updated by: dmitry@php.net Reported By: jadelucca at comcast dot net -Status: Assigned +Status: Bogus Bug Type: Scripting Engine problem Operating System: Windows XP PHP Version: 5.1.2 Assigned To: dmitry New Comment: The following code shouldn't be worked according to language specification, but worked before 5.1 because of side effect <?php function test(&$text) { $text = "Prefix " . $text; } test($x="A"); echo $x; ?> However the following code never worked <?php function test(&$text) { $text = "Prefix " . $text; } $y="A"; test($x=$y); echo $x; ?> I think we shouldn't keep such mess for BC and break language specification (the assignment $x="A" in first example is an expression and it can not be passed by reference). Previous Comments: ------------------------------------------------------------------------ [2006-01-15 22:16:32] derick@php.net Jani, I discussed this with Ilia earlier today and it *is* a BC breaking change in PHP 5.1.2 - all other versions do not do this (including PHP 4.4.x or 5.1.1). Therefore it is a bug and it should be addressed. Dmitry, if you feel otherwise, please close it then. ------------------------------------------------------------------------ [2006-01-15 19:56:24] sniper@php.net And you've reported it as PHP 5.1.2 bug which it STILL IS NOT. Please stop reopening this, we're not gonna change it. ------------------------------------------------------------------------ [2006-01-15 19:26:55] jadelucca at comcast dot net iliaa, did you read Derick's post? You're right; it's NOT a bug, in 5.1.2, that is. It is a bug in the 4.4.x version that it works in the first place without issuing errors. ------------------------------------------------------------------------ [2006-01-14 21:47:46] jadelucca at comcast dot net Thank you Derrick! I really appreciate your help. I will change my code not to do this... I thought you could since it issued no errors. ------------------------------------------------------------------------ [2006-01-14 19:59:58] derick@php.net It's not a bug in 5.1.2, but in earlier versions. PHP 4.4 still inhbits this bug though, in the form that it doesn't give an E_STRICT error. Dmitry, can you have a look at that? ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
