Uhhh, nope. That only works in your code if $b is initially 0. They're
shorthand for "do something and reassign".
$a = 100;
$a += 10; // $a = $a + 10
$a -= 10; // $a = $a - 10
$a /= 10; // etc...
$a += 10;
$a <<= 2;
$a .= ' is a weird number';
$mode = 0755;
$mode &= 01;

In PHP, what does the operator "-=" do?
$var -= 1 is the same as $var = $var - 1

Set's a negative value:
$a = 10;
$b -= $a;
or
$b -= 10;
In both cases $b will equal -10.
