Bug #71274 [NEW]: func_get_args() behaviour change in PHP 7

From: patrickallaert Operating system: PHP version: 7.0.1 Package: PHP Language Specification Bug Type: Bug Bug description:

func_get_args() behaviour change in PHP 7 Description: ------------

func_get_args() (and probably the related functions) are context sensitive in PHP 7.0 while it was not the case in PHP 5.x. If you change the content of one of your arguments and then call

func_get_args(), the change you made is reflected in the results you get, even if those were scalars. See the results at: https://3v4l.org/Ti8YX Might be a doc issue if we consider that this behaviour is "normal" but it doesn't look documented and as per issue #30207, we previously emphasized that "func_get_args() returns the arguments *passed* to the function". Test script: --------------- <?php function issueWithArgs($x) { $x = 33; return func_get_args(); } var_dump(issueWithArgs(42)); Expected result: ---------------- array(1) { [0]=> int(42) } Actual result: -------------- array(1) { [0]=> int(33) } -- Edit bug report at https://bugs.php.net/bug.php?id=71274&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=71274&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=71274&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=71274&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=71274&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=71274&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=71274&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=71274&r=needscript Try newer version: https://bugs.php.net/fix.php?id=71274&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=71274&r=support Expected behavior: https://bugs.php.net/fix.php?id=71274&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=71274&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=71274&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=71274&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=71274&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=71274&r=dst IIS Stability: https://bugs.php.net/fix.php?id=71274&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=71274&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=71274&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=71274&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=71274&r=mysqlcfg
