PHP PDO: Unable to connect, Invalid catalog name

Question

I am trying to set up a new site on my hosting (Host route if it matters) but i keep getting this error when i try using PDO (first PDO site im trying):

Fatal error: Uncaught exception 'PDOException' with message 'SQLSTATE[3D000]: Invalid catalog name: 1046 No database selected' in /home/kennyi81/public_html/gamersite/login.php:36 Stack trace: #0 /home/kennyi81/public_html/gamersite/login.php(36): PDOStatement->execute() #1 {main} thrown in /home/kennyi81/public_html/gamersite/login.php on line 36

When i use these settings:

$dbh = new PDO("mysql:91.146.107.11;dbname=kennyi81_gamersite", "kennyi81_gamer", "***************");
$dbh->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);

....

$stmt = $dbh->prepare('SELECT * FROM USERS WHERE ID = :id LIMIT 1');

How the database is laid out:

I am able to use mysqli connect fine on my other sub domains / main site, but i just cannot get PDO to work.

I've tried this, which i have seen around:

 $stmt = $dbh->prepare('SELECT * FROM gamersite.USERS WHERE ID = :id LIMIT 1');

but it retuns a syntax error.

Anyone have any idea what may be causing this?

This is all working on my local server, nothing changed on upload apart from connect line.

Answer 1

Instead of:

$dbh = new PDO("mysql:91.146.107.11;dbname=kennyi81_gamersite", "kennyi81_gamer", "***************");

Try:

$dbh = new PDO("mysql:host=91.146.107.11;dbname=kennyi81_gamersite", "kennyi81_gamer", "***************");

(add host=)

And it most likely works on your local server, because you have mysql:localhost... or mysql:127.0.0.1... there and it's ignored (cause it's missing host= aswell) and by default it's localhost.
