SYNOPSIS

       Warning

	      This  function  was deprecated in PHP 4.3.0, and will be removed in the future, along with the entirety of the original MySQL exten-
	      sion. Instead, the MySQLi or PDO_MySQL extension should be used. See also MySQL: choosing an API guide  and  related  FAQ  for  more
	      information. Alternatives to this function include:

		     oExecute a
		       DROP DATABASE query

       bool mysql_drop_db (string  $database_name, [resource  $link_identifier = NULL])

DESCRIPTION

       mysql_drop_db(3)  attempts to drop (remove) an entire database from the server associated with the specified link identifier. This function
       is deprecated, it is preferable to use mysql_query(3) to issue an sql DROP DATABASE statement instead.

	      o $database_name
		- The name of the database that will be deleted.

	      o $
		link_identifier -The MySQL connection. If the link identifier is not specified,  the  last  link  opened  by  mysql_connect(3)	is
		assumed. If no such link is found, it will try to create one as if mysql_connect(3) was called with no arguments. If no connection
		is found or established, an E_WARNING level error is generated.

	Returns TRUE on success or FALSE on failure.

       Example #1

		  die('Could not connect: ' . mysql_error());
	      }

	      $sql = 'DROP DATABASE my_db';
	      if (mysql_query($sql, $link)) {
		  echo "Database my_db was successfully dropped
";
	      } else {
		  echo 'Error dropping database: ' . mysql_error() . "
";
	      }
	      ?>

       Warning

       Note

	       For backward compatibility, the following deprecated alias may be used: mysql_dropdb(3)

       mysql_query(3).

		assumed. If no such link is found, it will try to create one as if mysql_connect(3) was called with no arguments. If no connection
		is found or established, an E_WARNING level error is generated.

	      set_time_limit(0);

	      $conn = mysql_connect('localhost', 'mysqluser', 'mypass');
	      $db   = mysql_select_db('mydb');

	      /* Assuming this query will take a long time */

	      if (!$result) {
		  echo 'Query #1 failed, exiting.';
		  exit;
	      }

	      /* Make sure the connection is still alive, if not, try to reconnect */
	      if (!mysql_ping($conn)) {
		  echo 'Lost connection, exiting after query #1';
		  exit;
	      }
	      mysql_free_result($result);

	      /* So the connection is still alive, let's run another query */
	      $result2 = mysql_query($sql2);
	      ?>
