I am adding some custom classes to a project. I am struggling to get psr-4 autoloading to work.

I am placing my custom classes in a folder at [project root]/lib Here is the autoload bit from my composer.json:

  "autoload": {
    "psr-4": {
        "App\\": "app/src",
        "Lib\\": "lib"
    }
},

I have a file P_Database.php in the lib folder with the following declarations:

 <?PHP
namespace Lib;

class P_Database
{
     //

I call the class in a file with:

 use Lib\P_Database;
 require __DIR__ . '/../vendor/autoload.php';
 $db = new P_Database();

I get a 500 error:

 PHP Fatal error:  Class 'Lib\\P_Database' not found....

I have run composer dump-autoload. Can anyone point me in the right direction?

does it work if you move the require statement above the use statement? – fire Apr 13 '16 at 16:26
@fire no. Tried it; same result. – Roger Creasy Apr 13 '16 at 16:28
have you run composer dump-autoload? – Hanson Apr 13 '16 at 16:35
Does the `App` namespace work properly ? Try adding a `/` at the end of your paths. – Kuba Birecki Apr 13 '16 at 16:40
@KubaBirecki Yes, App namespace works; tried adding training /, same result – Roger Creasy Apr 13 '16 at 16:46
con you show us your tree view of the folder that contain `composer.json`? – Federkun Apr 13 '16 at 19:30
All: thanks for your time. I have no idea why, but this morning, with no changes to my code, this is working correctly. – Roger Creasy Apr 14 '16 at 19:25
