I can't get a for loop to work!

set up php apache on my windows local machine

Parts of php are working just fine, but I was havin issue with a 4 loop so I made a really simple one and it doesn't work either. I get a Parse error...here is the code.

<?php
for ($distance = 50; $distance <= 250; distance += 50) {
echo $distance;
}
?>

Code (markup):

I get the following firefox error...

Parse error: parse error, expecting `')'' in C:\wamp\www\testing1\dbweb\chap1\pro1\freight.php on line 2

 

You missed a dollar sign on the 3rd distance.

 

Well, I am dumb... forgot my $ after 3rd distance...

 

hehe, silly mistakes like that have caused me hours of hunting before.

 

It's obviously a rather small grammatical error hard to spot.

Use an advanced IDE development environment for PHP like Zend. It would instantly point out grammatical errors after your typing of a whole line.
