blank screen

[gjm68]

Here is my php script

<?php
require ($_SERVER["DOCUMENT_ROOT"] . "/config/db_config.php");

$connection = mysql_connect($db_host, $db_user, $db_password) or die("Error Connecting");

echo "Connection Sucessful";
?>

When I run it my browser window is blank. If I comment out the $connection line then I get the words Connection Sucessful displayed in the browser. This appears to show that the php is working. It is only when I try to connect to the mysql server that I have the problem of a blank screen.

I am stuck, Please can anyone help me?. I am willing to email my php.ini or any other configuration filee if it helps.

thanks

First, we don't email each other files here. The whole purpose of doing this in an open forum is that each of us can learn from our fellow members' experience.

Does your PHP installation have MySQL available to it? Create a script on your web server which consists entirely of:

<?php
phpinfo();
?>

and point your browser at the script. Does the output mention MySQL at all?

What is the setting display_errors in your php.ini?

On what OS and with what web server are you running PHP?

Want the best answers? Ask the best questions!

TANSTAAFL!!

I ran phpinfo() on my browser

I am running the Apache 2 web server which appears to be working plus mysql 4.1.14

I am really stuck

Here is the result of phpinfo
