I've been learning PHP by reading all sorts of things on the web. I've trying to figure out what this is called so I can look it up and read about it and learn how it works. It's the "++" in the code I'm assuming counts up so that the codes knows when to do a new line. I not looking for corrections to this code I'm looking for what the "++" is called so I can look it up.

$i = 0
if (++$i == 10) {
    echo "new line";
}

It's called the prefix increment unary operator . It increments the number or character, then returns its value.

The postfix version does pretty much the same but returns its value first, then increments the variable.

That is a pre-increment. So in that code, $i is first incremented (increased by one), and then its value is used to test for equality to 10.

So the code that you show essentially tests if 1 equals 10 (which it does not.)

It is a number operator named the prefix increment. It takes the previous stated number and adds 1 to it. You can find more information about arithmatic operators here: Howtoforge.com
