Web Programming with PHP

23 Database Connection Library

mysql_connect() and mysql_select_db() are needed in different web pages with access to the database.

The connection and selection of the database are put in a different file:

db.php

<?php
$link = mysql_connect("localhost" , "root", "");

if($link == false) {
  echo "Error: can't connect to database server";
  exit;
}

if(mysql_select_db("minifacebook", $link) == false) {
  echo "Error: can't connect to database";
  exit;
}
?>
