i didn't understand nothing at all.
function &find_var($param)
{
/* ...code... */
return $found_var;
}
$foo =& find_var($bar);
$foo->x = 2;
echo $foo->x;
is getting the same result without the sign &
function find_var($param)
{
/* ...code... */
return $found_var;
}
$foo = find_var($bar);
$foo->x = 2;
echo $foo->x;
can someone give me some practical use of this, with the affects of this thing? because my
understanding is limited i guess :\
