Problem echoing variables

[RandGuy]

Im having a problem with a form script on my site, it grabs information from a database - this information is then echoed into a form. Each time I create a price_ variable and generate a number on to the end (e.g price_0,price_1) and this adds one each time. Now thats fine, but on the page that processes these variables I tried the following to display the price...

$price = "price_" . $i;

This doesnt work, so how would I dynamically create the right variable and be able to display it. I hope I explained it right, arrays arent an option, Im just looking for a solution to this current setup.

Nevermind... The following works...

$HTTP_POST_VARS[$num]

Welcome to WebmasterWorld RandGuy,

if your php version is > 4.1.0 you should use $_POST instead of $_HTTP_POST_VARS, this page may help in the future
