PHP4 to work in Apache (for WinNT) and MySQL

Well I got Apache running for WinNT, and now php3 extensions display the .php3 webpage(I've installed PHP4 though) - but they don't actually work I don't think because the database connect just displays the field and variable names and printf statements. I don't think Apache is actually running the PHP3 code because when I do a plain PHP3 file with PHP3 include statements the included files don't display at all and I get a blank page. If I'm right MySQL support is built into PHP4 so it's not that which isn't working, must be PHP itself. I've edited httpd.conf and put the following lines in - is this all I need to do - must be missing something AddType application/x-httpd-php-source .phps AddType application/x-tar .tgz AddType application/x-httpd-php3 .php3 AddType application/x-httpd-php3 .phtml This is what the official documentation says, but I think it refers to PHP3 only. I have PHP4, but still name my files .php3, they should still work anyway as no PHP4 features are used in them. Help J
