How to "include" one php file into another

[Ali_baba]

Hello there,

I have a code like this

$db_username = "student";
$db_password = "itk215";
$db_name =  "itk215";
$mysql_link = mysql_connect( "localhost", "$db_username", "$db_password") or die( "Unable to connect to database server");
@mysql_select_db( "$db_name") or die( "Unable to select database");
$res_pass = md5($passwrd);
$result = mysql_query("SELECT COUNT(*) FROM ktl WHERE user_name='$user_name' AND passwrd='$res_pass'"); 
$result_count = mysql_result($result,0,0); 

From line 1 till line 4, I want to have this information in some other php file so that I won't need to write this again and again. And I want this .php file to be included in other scripts. Can somebody please tell me how to do so?

Regards,

Taz

This is basic stuff - please read the manual.

It is best to use require() because if there is a problem with the connection, it will not let the site load. This will prevent information about query failures from being displayed to the public.
When using include, if not coded correctly, it will display paths and information about the issue to the user if you get a failure.
