Bug #55754 [NEW]: Only variables should be passed by reference for ZEND_SEND_PREFER_REF params

From: Operating system: PHP version: 5.3.8 Package: Scripting Engine problem Bug Type: Bug Bug description:Only variables should be passed by reference for ZEND_SEND_PREFER_REF params Description: ------------ Built-in functions where a parameter is defined with ZEND_SEND_PREFER_REF raises a Strict Standards warning if an expression is passed as the argument. The PREFER part signals the preference of passing by reference, but if the argument is not a variable, it should behave as if the parameter was defined with ZEND_SEND_BY_VAL and keep quiet, just as for regular ZEND_SEND_BY_VAL parameters. Test script: --------------- <?php error_reporting(32767); current($arr = array(0 => "a")); /* Strict Standards: ... */ current(array(0 => "a")); current($arr); ?> Actual result: -------------- Strict Standards: Only variables should be passed by reference in filename on line 5 -- Edit bug report at https://bugs.php.net/bug.php?id=55754&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=55754&r=trysnapshot54 Try a snapshot (PHP 5.3): https://bugs.php.net/fix.php?id=55754&r=trysnapshot53 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=55754&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=55754&r=fixed Fixed in SVN and need be documented: https://bugs.php.net/fix.php?id=55754&r=needdocs Fixed in release: https://bugs.php.net/fix.php?id=55754&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=55754&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=55754&r=needscript Try newer version: https://bugs.php.net/fix.php?id=55754&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=55754&r=support Expected behavior: https://bugs.php.net/fix.php?id=55754&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=55754&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=55754&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=55754&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=55754&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=55754&r=dst IIS Stability: https://bugs.php.net/fix.php?id=55754&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=55754&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=55754&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=55754&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=55754&r=mysqlcfg
