Req #69223 [Opn]: passing extra parameters in function/method call

Edit report at https://bugs.php.net/bug.php?id=69223&edit=1 ID: 69223 Updated by: aharvey@php.net Reported by: php at w3x4 dot com Summary: passing extra parameters in function/method call Status: Open Type: Feature/Change Request Package: Scripting Engine problem Operating System: W7 64 PHP Version: 5.6.6 Block user comment: N Private report: N New Comment: Yeah, that feels like an IDE and/or xdebug issue rather than a PHP one. Previous Comments: ------------------------------------------------------------------------ [2015-03-11 20:17:53] php at w3x4 dot com Thanks- I'm in support of the RFC. However, this still leaves the matter of why $a is not displayed during breakpoint. As I think more about it, maybe that's an xdebug issue? ------------------------------------------------------------------------ [2015-03-11 20:09:22] aharvey@php.net This is supported because PHP 5.5 and earlier used this for variadic functions, so at present this is expected behaviour. There's an open RFC at present which would address this: https://wiki.php.net/rfc/strict_argcount. I'll move this to a feature request pending the outcome of that RFC. ------------------------------------------------------------------------ [2015-03-11 20:06:11] php at w3x4 dot com Description: ------------ /* Using Visual Studio 2013 with Devsense PHP Tools, or * Using UEStudio 15: * * 1) Set breakpoint on the 3 lines containing: $c=2 * * 2) Examine Locals window to confirm that $a does not appear when a static call or a function call passes more variables than the called method/function expects. * * 3) Examine the error log to confirm that php does not throw an error or report a warning. * * 4) Note that the existence of a reference to $a in Class Two results in $a being displayed in the Locals window. Note also that removing '$b=1' will result in $a being displayed in Locals window. * * I suggest that PHP should throw a fatal error when passing more parameters than the function/method expects; it seems some other (related) php problem is the cause of $a not being displayed in Locals window. * * * <SAA> */ Test script: --------------- $xyz = new Class1; class Class1 { public function __construct() { $this->_callHook(); } function _callHook(){ $ret = One::f1('a'); $ret = f1('b'); $ret = Two::f1('a'); } } class One{ static function f1(){ $a=1; $b=1; $c=2; } } function f1(){ $a=1; $b=1; $c=2; } class Two{ static function f1(){ $a=1; $b=1; $c=2; echo $a; } } ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=69223&edit=1
