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??
