Notice: Use of undefined constant

[soma56]

I'm attempting to learn how to connect PHP with MySQL. The sample materials I'm learning from don't have any display issues, however, when I run the code I receive the following error:

 

Notice: Use of undefined constant db - assumed 'db' in C:\mypath\databases.php  on line 4

 

My code is relatively simple and I should note that I'm completely new to learning this stuff.

 

<?PHP
//1. Create a database connection
$db = mysql_connect("localhost", "root", "mypassword");
if (!db) {
	die("Database connection failed: " . mysql_error());
}
?>

 

Suggestions?

You forgot the '$' infront of your variable

<?php
if (!$db) {
?>
