Bug #70379 [NEW]: call_user_func_array only accepts explicit references

From: lolautruche at gmail dot com Operating system: OSX PHP version: 7.0.0RC1 Package: Unknown/Other Function Bug Type: Bug Bug description:call_user_func_array only accepts explicit references Description: ------------ In PHP 7, passing variables assigned by reference to call_user_func_array() (as part of arguments) now triggers a warning : "Warning: Parameter 1 to ... expected to be a reference, value given in..." It worked fine in PHP 5.6. Current workaround is to explicitly pass the value by reference (see code). Not sure if this is on purpose, but I couldn't find any mention in the UPGRADING doc about this specifically. Test script: --------------- <?php $foo = function (&$arg) { var_dump($arg); }; $a = 'bar'; $b =& $a; // Warning: Parameter 1 to {closure}() expected to be a reference, value given in /Users/lolautruche/Desktop/reference.php on line 8 call_user_func_array($foo, [$b]); // Works fine call_user_func_array($foo, [&$a]); Expected result: ---------------- string(3) "bar" string(3) "bar" Actual result: -------------- Warning: Parameter 1 to {closure}() expected to be a reference, value given in /Users/lolautruche/Desktop/reference.php on line 10 string(3) "bar" -- Edit bug report at https://bugs.php.net/bug.php?id=70379&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=70379&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=70379&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=70379&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=70379&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=70379&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=70379&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=70379&r=needscript Try newer version: https://bugs.php.net/fix.php?id=70379&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=70379&r=support Expected behavior: https://bugs.php.net/fix.php?id=70379&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=70379&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=70379&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=70379&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=70379&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=70379&r=dst IIS Stability: https://bugs.php.net/fix.php?id=70379&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=70379&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=70379&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=70379&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=70379&r=mysqlcfg
