DB Connection error! Please help me

[Brian Ross]

I have a hw assignment in which i need to u/l an html and php file to a server that allow a person to create,delete,insert and view a product table. Im using easyphp 1.8 to act as a virtual server on my pc and i've gotten it so that everything works great on my computer. But when i try to upload the files and then click any of the SQL buttons i get this error:

Warning: mysql_connect() [function.mysql-connect]: Unknown MySQL server host 'localhost/students' (1) in /home/genit17ure/public_html/query.php on line 28

Now originally the prof wanted us to use PEAR but she said that we didn't have to. In our assignment she told us to connect to a DB called students and my specified table is genit17ure. the PEAR DB connection string she gave me is
$db = DB::connect('mysql://genit17ure:243157@localhost/students');

so i tried to translate that to sql using the following code:

$db="students";

$link = mysql_connect("localhost/students", "genit17ure", "243157");

if (! $link)

die("Couldn't connect to MySQL");

mysql_select_db($db , $link)

or die("Select DB Error: ".mysql_error());

Can you figure out what im doing wrong cuz this is killing me.
