Note Submitter: Anonymous ---- "As of PHP 5.3.0, you will get a warning saying that "call-time pass-by-reference" is deprecated when you use & in foo(&$a);." Actually it will be better the other way. To make sure foo($a) generates a warning whereas foo(&$a) does not. That way the user of the function will know that $a is going to be modified. Whether a variable will be modified should be obvious from the way the function is called without needing to look up the function definition.
