Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to
report
a bug at http://bugs.php.net/how-to-report.php
With an expression like
do_something($foo = 'bar');
the behavior is undefined. We don't guarantee i which order the function
call and the assignment are being executed. This might change any time.

Description:
------------
for this code when you run in php4, the app will output "func", but
under php5 your will get another result -- "php"
I don't know why.
Test script:
---------------
<?php
function func(&$param){
$param = "func";
}
func($param="php");
echo $param;
?>
Expected result:
----------------
func
Actual result:
--------------
php
