In 7.4, both lines throw a warning. <?php $foo=null; $foo->bar = "baz"; // does throw warning in <7.4 $foo=null; $foo->bar["baz"] = "baz"; // doesn't throw warning in <7.4 I'm not asking for the old obviously broken behavior to be restored, but seeing that some still somewhat widely used piece of software is relying on this bug, it may make sense to add a note to the UPGRADING.txt file. Test script: --------------- <?php $foo=null; $foo->bar = "baz"; // does throw warning $foo=null; $foo->bar["baz"] = "baz"; // doesn't throw warning Expected result: ---------------- one warning Actual result: -------------- two warnings ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=78645&edit=1
