There are couple of things, you to verify and correct.
First of all, your database connection code, that doesn't seems to be correct. I didn't see any condition on which you are suppose to invoke die
.
$connect = mysql_connect('localhost', 'root');
{
die ("Unable to connect to database<br>");
}
From the above code, below line will execute all the time
die ("Unable to connect to database<br>");
You should correct your database connection code to below :
$link = mysql_connect('localhost', 'mysql_user', 'mysql_password');
if (!$link) {
die('Could not connect: ' . mysql_error());
}
echo 'Connected successfully';
mysql_close($link);
You can refer mysql_connect for the usage.
Also, verify your file extension is .php
