thank you for the reply.

i had a small misunderstanding regarding variable reference...now its clear

but..

the output of

<?php
$x = 1;
$a1 = array(&$x);
var_dump($a1);
?>

is
array(1) {
  [0]=> &int(1)
}

while for

<?php
$x = 1;
$a1 = array(&$x);
var_dump($a1[0]);
?>

it is

int(1)

can u tell me what & signifies here??
