A better PHP class file autoloader library than PSR.

• PSR Specifications are so badly! Totally can't as a standard even or a suggestion because it too loosely and personalized customization.
• For the first reason, Composer is terrible too, it makes the PHP world messing.
• Conveniently to using and simply, scientific rules.
• Also good performance.

Download the LoaderOne source code floder placed it in your project dir anywhere, commonly at project root dir is ok.

• Setting the third-party "Class" lookup paths of the project dir in find_path.php (.e.g: Assume a thrid-party class fully qualified class is \Acme\Log\Writer\File_Writer, and you can place it at "Vendors" or "Library" or whatever else dir, so you need specify for this case.)

• Add below code in your entry PHP file, commonly is index.php, and classes can auto loaded.

...


$autoLoader = include_once 'LoaderOne\Autoloader.php';
$autoLoader->setBasePath(`YOUR_PROJECT_ROOT_DIR`);

...

• Allow LoaderOne dir can writeable.

PHP 5.3+

1. Keep the "Namespace" completely mapping the actual directory's hierarchy.

2. Keep the "Class" and "Namespace" naming & capitalized same as the located directories name.
