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;
}
?>
