I don't know what PHP's offic
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?

$b -= 10;
In both cases $b will equal -10.

It returns a remainder. For example 7 % 2 = 1.

There are plenty of situations where it's useful. For example, if you're
displaying data in rows and want to shade every other row:
It doesn't have a use in only PHP but in all programming languages.
It's a math thing .. u can get a remainder of a division.
10%8 = 2
12%8 = 4
10%5 = 0
12%5 = 2
Simple application:
$ppl = 23;
$grpsize = 7;
echo ("when $ppl people are divided over groups of $grpsize, ".
$ppl%$grpsize ." people a
9 matches
