Error: Call to undefined function mysql_connect()

[robert balneaves]

Hi Guys,

Ive slowly been teaching myself html and have now moved on to php and mysql. For the last few hours ive been trying to connect to a database ive created however i keep getting the following

Fatal error: Uncaught Error: Call to undefined function mysql_connect() in C:\wamp64\www\Intranet\demo.php on line 6

Error: Call to undefined function mysql_connect() in C:\wamp64\www\Intranet\demo.php on line 6

the code im using is

<?php
$link = mysql_connect('localhost', 'root', '');
if (!$link) {
die('Could not connect: ' . mysql_error());
}
echo 'Connected successfully';
mysql_close($link);
?>

Its driving me mad does anyone have any ideas? thanks in advance
