NEWB: Easy database connection variable question
Posted: Fri Jun 19, 2009 7:27 pm
Here's the code....
<?php // db.php
$dbhost = "localhost";
$dbuser = "user";
$dbpass = "password";
function dbConnect($db="law") {
global $dbhost, $dbuser, $dbpass;
$dbcnx = @mysql_connect($dbhost, $dbuser, $dbpass)
or die("The site database appears to be down.");
if ($db!="" and !@mysql_select_db($db))
die("The site database is unavailable.");
return $dbcnx;
}
?>
The instructions say :
The function begins by connecting to the MySQL server using the $dbhost, $dbuser, and $dbpass variables at the top of the file (you'll need to set these to appropriate values for your server), and then if a database name was given it selects that database.
My question is, do I replace the global variable names listed on the line below with the actaul hostname, user, and password, do I put a $ before the actaul hostname, etc?
$dbcnx = @mysql_connect($dbhost, $dbuser, $dbpass)
Thanks in advance
