How To Connect to a MySQL Server with Default Port Number in MySQL?

If you want to connect a MySQL server with default port number, you can use the "mysql_connect($server)" function, where $server is the host name or IP address where the MySQL server is running. If successful, mysql_connect() will return a connection object for you to allow you to run other MySQL API functions.

The tutorial exercise below shows you a simple connection call to a MySQL server on the "localhost":

<?php
  $con = mysql_connect('localhost');
  if (!$con) {
    print("There is a problem with MySQL connection.\n");
  } else {
    print("The MySQL connection object is ready.\n");
    mysql_close($con); 
  }
?>

But this will not work, if your server is running a non-default port number, 3306. In that case, It will give this output:

PHP Warning:  mysql_connect(): Can't connect to MySQL server
   on 'localhost' (10061) in fyi_center.php on line 2
There is a problem with the MySQL connection.
