[PHP] Tutorial Two Numbers - KyleFYI - 02-21-2013
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.

Code:<?php function add($n1,$n2) { echo $n1 + $n2; } add(4,6); ?>
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.
