PHP from the Browser?

I'm a clueless newbie who just downloaded php-4.3.0-Win32 to Win 98, and am having multiple problems. 1. When I click on the manual's test program ("Hello World") in IE 6.0, it brings up a MSDOS box, rather than execute the php file. I can't find anything in the manual that says how to get a php file to operate locally from a browser. Any Suggestions? 2. Also, I found that in order to get cli/php.exe to execute from the command line, I had to copy php4ts.dll into the cli directory. So maybe that's a bug in the installation program. 3. But when I aimed cli/php.exe at the test file, it just echoed the code, rather than execute it! Huh? 4. I uploaded the test file to my host, who's running a v. 4.3.0.3 server and got the error message that the parser expected a '('' on line 11. The code is: <html> <head> <title>PHP Test</title> </head> <body> <?php echo "Hello World<p>"; ?> </body> </html> so there is no line 11! Even when I gave it parens: <html> <head> <title>PHP Test</title> </head> <body> <?php echo ("Hello World"); ?> </body> </html> I got the same error message. All suggestions will be welcomed! Harvey
