NEED HELP Incrementing a variable name

Hi I can't find info on how to achieve the following:

I want to increment through the variable names I've already set.
Specifically $general_image1, $general_image2 & $general_image3

I need something like this code (that works !!)

for($i=1; $i<4; $i++)
{
if($general_image[$i] != "&nbsp;")
{
blah blah...
}
}

Kindly answered by "Peter van Schie" in alt.php

<?php
for($i=1; $i<4; $i++)
{
if (${"general_image".$i} != "&nbsp;")
{
// blah blah...
}
}
?>

Cheers Nitrous
