[PHP] Tutorial Two Numbers

So, using numbers in php is very easy. Remember though coding always starts from 0 not one.

So to add lets say 1 + 1 you'd do it like this.

PHP Code:

<?PHP
    $number1 = 1;
    $number2 = 1;
    $number3 = $number1 + $number2;
    echo $number3;
?>

This would just echo out "2" that's all.

Lets say if you'd like to multiple 5 by 5 you'd do it like this.

PHP Code:

<?PHP
$number1 = 5;
$number2 = 5;
$number3 = $number1 * $number2;
echo $number3;
?>

See I am using * to multiple it, and not a x. But all this will echo out is "25".

There are a lot more witch you should be able to work out on your own.

Note: If you need any help and I have not yet made a tutorial for it please visit php.net.

You should mention that you are using 'operators', not just 'adding' or 'multiplying' numbers.

Wouldn't it be better to teach using functions? It's so much easier than having to edit $number1 + $number2 every time, plus you can use the "add()" function I created below as many times in the code as you want.

If you look at my other tutorials you'll see I have done on on functions.

Instead of using functions or so, if you only want to add by one, just write the variables name followed by ++. Also, you should put all your tutorials in one thread instead of making a bunch of them.

This isn't adding by one though.
But yes, $int++; works perfectly.

It isn't? Oh well.

It's not, because the other half of the thread is 5+5. And I'm pretty sure he wouldv'e said $number1++; if he wanted to show more about specifically adding 1, rather than any number in general.
