Bug #74745 [Opn->Csd]: Incorrect ReflectionFunction information for array_multisort

Edit report at https://bugs.php.net/bug.php?id=74745&edit=1 ID: 74745 User updated by: tandre at themeetgroup dot com Reported by: tandre at themeetgroup dot com Summary: Incorrect ReflectionFunction information for array_multisort -Status: Open +Status: Closed Type: Bug Package: Arrays related PHP Version: Irrelevant Block user comment: N Private report: N New Comment: I misread the documentation. This issue is incorrect, the parameters are really sorted bool array_multisort ( array &$array1 [, mixed $array1_sort_order = SORT_ASC [, mixed $array1_sort_flags = SORT_REGULAR [, mixed $... ]]] ) could possibly be changed to the below to make it less confusing, but that's unrelated bool array_multisort ( array &$array1 [, mixed &$array1_sort_order = SORT_ASC [, mixed &$array1_sort_flags = SORT_REGULAR [, mixed &$... ]]] ) Previous Comments: ------------------------------------------------------------------------ [2017-06-11 20:10:46] tandre at themeetgroup dot com Description: ------------ ReflectionFunction incorrectly states that $sort_order and $array1_sort_flags are passed by reference, not by value. This doesn't make sense, and is inconsistent with the documentation at https://secure.php.net/array_multisort See https://3v4l.org/sZcuu Test script: --------------- <?php $functionName = 'array_multisort'; printf("Params of %s:\n", $functionName); foreach ((new ReflectionFunction($functionName))->getParameters() as $param) { printf("Param \$%s: isPassedByReference=%s, isOptional=%s, isVariadic=%s\n", $param->getName(), var_export($param->isPassedByReference(), true), var_export($param->isOptional(), true), var_export($param->isVariadic(), true)); } Expected result: ---------------- ... otherwise unchanged Param $sort_order: isPassedByReference=false, isOptional=true, isVariadic=false Param $sort_flags: isPassedByReference=false, isOptional=true, isVariadic=false ... otherwise unchanged Actual result: -------------- Params of array_multisort: Param $arr1: isPassedByReference=true, isOptional=false, isVariadic=false Param $sort_order: isPassedByReference=true, isOptional=true, isVariadic=false Param $sort_flags: isPassedByReference=true, isOptional=true, isVariadic=false Param $arr2: isPassedByReference=true, isOptional=true, isVariadic=true ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=74745&edit=1
