Prefix PHP libraries and projects

Install any library freely. PHP-Prefixer will manage your namespaces.

PHP-Prefixer is an automated online service, powered by a complex rule-based system to apply prefixes to Composer dependencies.

Same libraries across all platforms

Develop your solutions using the same libraries for all the platforms you work in, specifically WordPress, Joomla, Drupal, Laravel, Symfony, Slim Framework, etc.

Composer + WordPress

Use Composer for your WordPress projects. PHP-Prefixer will process the dependencies to run smoothly along with other third-party plug-ins.

Fully integrated with Git

Declare your name space configuration and let the service produce the packages. No local installation. No Phars. No new dependencies.

Tailor the namespaces according to your needs

PHP-Prefixer grants you control of PHP libraries namespaces.

Prefix the namespaces

Automatically create your own versions of the best open source libraries.

namespace Carbon;

use Carbon\Exceptions\InvalidDateException;
use DateInterval;
use Symfony\Component\Translation;

class Carbon extends DateTime
    const NO_ZERO_DIFF = 01;
namespace ACME\Carbon;

use ACME\Carbon\Exceptions\InvalidDateException;
use DateInterval;
use ACME\Symfony\Component\Translation;

class Carbon extends DateTime
    const NO_ZERO_DIFF = 01;

Prefix all the usual cases at once

PHP-Prefixer is an rule-based expert system that processes the projects intelligently to define new namespaces.

Take into account functions, helpers, traits, interfaces, etc

Automatically create your own versions of the best open source libraries.

use Illuminate\Container\Container;

if (! function_exists('abort')) {
    function abort($code, $message = '')
        return app()->abort($code, $message, $headers);

if (! function_exists('app')) {
    function app($make = null)
use ACME\Illuminate\Container\Container;

if (! function_exists('ACME_abort')) {
    function ACME_abort($code, $message = '')
        return ACME_app()->abort($code, $message, $headers);

if (! function_exists('ACME_app')) {
    function ACME_app($make = null)
