But, it causes a StrictStandards warning. Separating it into two statements: $dummy=0; foo($dummy); of course works. Test script: --------------- <? function foo(&$a){ } foo($dummy=0); Expected result: ---------------- No warning. Actual result: -------------- Strict Standards: Only variables should be passed by reference in .. on line 4 ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=63994&edit=1
