Description:
------------
"The behaviour of functions with by-reference parameters called by value
has changed. Where previously the function would accept the by-value
argument, a warning is now emitted and all by-ref parameters are set to
NULL."
I find this ambiguous/difficult to understand.
"The behaviour of functions with by-reference parameters..."
Ok. This is a function "with by-reference parameters..."
<?php
function a( &$param ){
}
?>
"..called by value has changed. Where previously the function would accept
the by-value argument"
Ok. This is "would accept the by-value argument..."
<?php
a(2); //2 is a literal
?>
But this is illegal even in 5.2.
So, I suppose this what is meant by "..called by value..."
<?php
a($someVariable);
?>
"a warning is now emitted and all by-ref parameters are set to NULL"
So, this would cause a warning, and all by-ref paramaters are set to
NULL?
Thanks
