[RESOLVED] Increment Operator problem

belsk

Hey guys!
Why the output of this code is 10 and not 11? although i have used increment operator. :mad:

<html>
<body>
<?php
$x=10;
echo $x++;
?>
</body>
</html>

Observe that you used post-increment, so the result of the expression is the original value, not the incremented value.

So what do you think i should do to get the desired output?
I mean i don't want to use the following code

<?php
$x=10;
echo $x+1;
?>

Note: I am new to php and today's my second day of learning it, and the only computer languages i know are html, css & java script. Although i am out of practice for about 3 years.

Actually, echo $x + 1; is probably what I would do. If not:

<?php
$x = 10;
echo ++$x;

but it is pointless to change $x when you do not use it thereafter.

Oh thank! that's it.
I should've used ++$x instead of $x++

<?php 
$x = 10; 
echo ++$x;
?>

This problem is now solved 🙂

at first i didn't correctly understood what did you mean by post-increment.
Now i have understood.
