PHP Scoper for Wordpres Plugin Setup

This setup can be used to prefix classnames, say for a wordpress plugin.

Install php-scoper

install globally not within you package.

composer global require php-scoper --with-all-dependencies

Configure php-scoper

Create the scoper.inc.php file

php-scoper init

Customize scoper.init.php

In my case i have my psr-4 namespaced class in ./lib, so, I modified scoper.inc.php,

FIND    -> Finder::create()->files()->in('src'),
REPLACE -> Finder::create()->files()->in('lib'),

Run script scope.sh

cd /path/to/project
chmod +x ./scope.sh
./scope.sh

Require the php-scoper autoloader

Instead of requiring vendor/autoload.php I include vendor/scoper-autoload.php which also includes the standard autoloader.

Option 1) Just require the file

 require_once __DIR__ . '/vendor/scoper-autoload.php';

Option 2) Sometimes you just want to start working without running scoper, so, this works wel for that situation.

// autloading scoped vs. unscoped
if ( file_exists( __DIR__ . '/vendor/scoper-autoload.php' ) ) {
    require_once __DIR__ . '/vendor/scoper-autoload.php';
} else {
    require_once __DIR__ . '/vendor/autoload.php';
}

How to validate that scoper did it's job?

<?php
 $loader = require_once __DIR__ . '/vendor/scoper-autoload.php';
 print_r( $loader->getClassMap() );
 exit;
