Failed to connect to MySQL: (2003) Can't connect to MySQL server on 'localhost' (10061)

[Jav Carr]

Hi,
I´m using MAMP with PHP and Mysql server
I get an error message when I try to open the database using php.
The error message is:
Failed to connect to MySQL: (2003) Can't connect to MySQL server on 'localhost' (10061)

And the php code used is:

<?php
$mysqli = new mysqli("localhost", "javier", "", "ejemplo");
if ($mysqli->connect_errno) {
echo "Failed to connect to MySQL: (" . $mysqli->connect_errno . ") " . $mysqli->connect_error;
}
echo $mysqli->host_info . "\n";

?>

Can anyone help, please?
many thanks Jav
