Although the below is very simple it can be a very useful and effective way to regularly check apache functionality and its ability to communicate with mysql.
<html>
<head>
<title>Test mysql communications</title>
</head>
<body>
<!--test-->
<?php
$dbhost = 'localhost:3306';
$dbuser = 'trunty';
$dbpass = 'password';
$conn = mysql_connect($dbhost, $dbuser, $dbpass);
if(! $conn)
{
die('Could not connect: ' . mysql_error());
}
echo 'Connected successfully';
mysql_close($conn);
?>
</body>
</html>
A URL that this can be seen in action is http://dev.linuxismybff.com/test/mysql/mysqltestconnect.php
