Hi guys, i received a strict error, but i`m confused what function received...

Why I'm receiving a variables should be passed by reference when i use t($a=1)? the t() function received 1, or the variable $a with value = 1?

Test script:
---------------
<?php
error_reporting(E_ALL);
function t(&$a){}

t($a=1); /// should not receive error!! t() received ($a=1)? or t received (1) without variable $a reference?
?>

[beto@conquista2 ~]# php t.php

Actual result:
