Is PHP Caching my pages?

[Anon]

Hey all,

I have discovered a problem after upgrading to 4.0.6. Every time I make a change to a php script, the changes won't show up until I restart apache. Is there some sort of caching going on that I can turn off?
Thanks

As a follow up:

After I re-start apache, the first time I access my website I get this error:

Fatal error: Cannot redeclare s_include() in /home/httpd/php-lib/wcphp/wc.inc on line 57

Does that have something to do with the page update problem?

Add this code to your script:

header("Cache-control: no-cache, must-revalidate");
header("Pragma: no-cache");
