Rob Allen's Zend Framework 2 Tutorial: PHP Fatal error: Class 'Album\AlbumTable' not found

Question

I hope someone can help me with this.

I am working my way through Rob Allen's Zend Framework 2 Tutorial.

When I try to go to:

http://localhost/album/index

I get the following error:

Note it is saying Class 'Album\AlbumTable' not found even though AlbumTable.php is in Album\Model.

}

My configuration:

• Windows 7.
• Zend Server CE Technology Preview (PHP 5.4) (Note I have tried using Zend Server CE (PHP 5.3) but get the same error).
• Apache and MySQL work fine for other PHP pages, e.g. I can connect to the 'album' table using PDO in a simple PHP script.

Do any of you have any idea what the problem might be?

Answer 1

Replace your line with

$table = new \Album\Model\AblumTable($dbAdapter);

Or add a use on top of file before the class.

use Album\Model\AlbumTable;

Answer 2

Class is Album\Model\AlbumTable but in error message it is Album\AlbumTable

Stack trace leading you to ServiceManager. Closure for Album\Model\AlbumTables added to ServiceManager in Album\Module::getServiceConfig()

There you can see $table = new AlbumTable($dbAdapter); while namespace is Album it resolves to Album\AlbumTable.
This is easy to fix: add use Album\Model\AlbumTable; to module\Album\Module.php after namespace declaration
