PHP namespace/class not found with composer

Question

I created my first PHP library to host on GitHub.

https://github.com/TBETool/password-generator

on installing the library in my PHP Application using composer, the directory structure is like vendor

|- tbetool
   |- php-password-generator
      |- src
         |- PasswordGenerator.php
      |- README.md
      |- composer.json

Content of composer.json is

{
    "name": "tbetool/php-password-generator",
    "type": "library",
    "homepage": "http://thebornengineer.com",
    ],
    "require": {
        "php": ">=5.3.0"
    }
}

content of PasswordGenerator.php

<?php
namespace TBETool;

/**
 * Class PasswordGenerator
 * @package TBETool
 */
class PasswordGenerator
{
   // content goes here
}

and entry in my project's composer.json at /composer.json

"require": {
    "php": ">=5.6",
    .... other packages....
    "tbetool/php-password-generator": "^1.2"
},

But when I use in my program.

<?php

use TBETool\PasswordGenerator;
class MyClass {
   function myFun() {
       $password = new PasswordGenerator();
   }
}

But it gives error as

Class 'TBETool\PasswordGenerator' not found

Is there something error with setting up my library to be used using composer?

I've never written a library but I presume you need an autoload section somewhere in your composer.json file. How do you load classes when using it locally? — Álvaro González

You should use a psr-4 autoloading in your composer.json file

"autoload": {
    "psr-4": {
        "Namespace\\": "root/path/for/namespace"
    }
}

then dump your autoload composer dump-autoload
