Hi, I installed apache with support of php as i found om the online manual at php.net. I created a simple php file named hello.php <html> <head> <title>PHP Test Page</title> </head> <body> <?php echo "Hello <p>"; ?> </body> </html> and i the file in my htdocs directory i restarted apache and when i'm trying to access the page http://localhost/hello.php as a result i'm getting the contents of the file hello.,php which are: <html> <head> <title>PHP Test Page</title> </head> <body> <?php echo "Hello <p>"; ?> </body> </html> What is wrong is my apache able to display php pages? Thanx for your time!
