Re: [PHP-DEV] Interesting result

It doesn't matter because the behavior here is undefined just like in C.
You can't use a variable and it's post/pre increment value in the same expression.

 Hi,
i got an interesting case  :

<?php
$a = 1;
var_dump($a + $a++);


$a = 1;
$x = &$a;
var_dump($a + $a++);

?>
Result
int(2)
int(3)

Can somebody explain why if there is reference to the var the result is
different?
