[PHP] Weird results from Left Shift

[Sheridan Saint-Michel]

Okay, from the manual I have
$a << $b - Shift the bits of $a $b steps to the left

When I run the code

<?php
$num = "0001000";
echo "Number is $num<BR>";
$num = $num << 1;
echo "Shifted Number is $num";
?>

I get the output

Number is 0001000
Shifted Number is 2000

What am I missing?!?
