Answer / modi[achir communication]
<?
$a=5;
$b='a';
$$b=100;
$b is a simple variable and $$b is a reference variable that
means in memory $$b will be refer to $b. Suppose in memory
$b variable is in address 100 then $$b will be refer $b at
address 100 that means $$b will contain 100.

Answer / annonymus
<?php
$a=5;
echo $b='a'."<br/>";
echo $$b;
?>
output is neither 5 or 100,
it displays
a
but if you try this...
<?php
$user = 'bob';
$holder = 'user';
echo $$holder;
?>
answer becomes like this..
bob
try it....this really really confusing..anyone can give the
exact solution to this????

Answer / mr.kishore
<?php
$a=5;
$b='a';
$$b=100; // at this point $b='a' and when we use $ after
that '$$b becomes $a and we asign this value = 100 so $a
becomes 100;
echo $a;
