php can't recognize table from phpMyAdmin - php

Question

I created tables in phpMyAdmin - but when I try to connect php to the table it says:
can't use college unknown database 'college'
I was trying to move a zip file to the folder where the php file is (using xampp):
<?php
define('DB_NAME','college');
define('DB_USER','root');
define('DB_PASSWORD','');
define('DB_HOST','localhost');
$link=mysql_connect(DB_HOST,DB_USER,DB_PASSWORD);
if(!$link){
die('couldnt connect:'.mysql_error());
}
$db_selected=mysql_select_db(DB_NAME,$link);
if(!$db_selected){
die('can use'.DB_NAME.':'.mysql_error());
}
echo 'connect successful';
?>

First:
Confirm that you are accessing phpMyAdmin on the correct host. In your code, it's clear that PHP is attempting to connect to MySQL on localhost. Is phpMyAdmin running on localhost? If not, then you've identified your error - ensure that you are connecting to the correct server - wherever you are running phpMyAdmin.
Second:
If you're sure that you are running phpMyAdmin on the same host as you're trying to connect to with your php, then double-check that the correct database actually exists.
Connect to phpMyAdmin, and select the tab labeled 'SQL' at the top. In the query box, enter SHOW DATABASES;, then select the 'go' button underneath the query box.
On the results page, ensure that your 'college' database exists. If it's not listed in the results, then you will need to re-create the database.
Otherwise, it's likely a permissions issue with your user (root) accessing your 'college' database.
