Receiving database issue PHP PDO - php

Question

So I've just set up an old script of mine which works fine on all the web hosts I've tried but one (including localhost).
Anyhow, I've set up the database and it's connected (I've tried the connection and it should work fine), though I am recieving an error that my site can not connect to the database.
I am receiving the PDOException message no matter what.
config.php
<?php
require "details.php";
try {
$dbh = new PDO("mysql:host=$hostname;dbname=$database", $username, $password);
}
catch(PDOException $e)
{
echo 'Your website can not connect to the database';
}
details.php
<?php
$hostname = 'localhost';
$username = 'myuser';
$password = 'mypassword';
$database = 'mydatabase';
define('DB_NAME', 'mydatabase');
define('DB_USER', 'myuser');
define('DB_PASS', 'mypassord');
define('DB_HOST', 'localhost');
I've come to the conclusion that it must be one of those codes that it must be something to do with the above code.
I have tried this code below to make sure the PDO extention is enabled and yes it is.
<?php
if (!defined('PDO::ATTR_DRIVER_NAME')) {
echo 'PDO unavailable';
}
elseif (defined('PDO::ATTR_DRIVER_NAME')) {
echo 'PDO available';
}
Any idea, maybe why?

Get rid of that catch stuff.
Leave only three lines in this file
<?php
require "details.php";
$dbh = new PDO("mysql:host=$hostname;dbname=$database", $username, $password);
and see what does it say, either on screen or in log, according to site settings.
