README

This is expandable dbgp xdebug proxy based on amphp.

The idea is described in the document Multi-user debugging in PhpStorm with Xdebug and DBGp proxy.

The main benefit is that this proxy is written in php - the language you know.

Installation

This package can be installed as a Composer project:

composer.phar create-project mougrim/php-xdebug-proxy

Or dependency:

composer.phar require mougrim/php-xdebug-proxy --dev

For parse XML you should install ext-dom.

For write logs by default you should install amphp/log (use --dev if you installed php-xdebug-proxy as dependency):

composer.phar require amphp/log '^1.0.0'

Run

You can run next command:

bin/xdebug-proxy

The proxy will be run with default config:

Using config path /path/to/php-xdebug-proxy/config
[2019-02-14 10:46:24] xdebug-proxy.NOTICE: Use default ide: 127.0.0.1:9000 array ( ) array ( )
[2019-02-14 10:46:24] xdebug-proxy.NOTICE: Use predefined ides array (   'predefinedIdeList' =>    array (     'idekey' => '127.0.0.1:9000',   ), ) array ( )
[2019-02-14 10:46:24] xdebug-proxy.NOTICE: [Proxy][IdeRegistration] Listening for new connections on '127.0.0.1:9001'... array ( ) array ( )
[2019-02-14 10:46:24] xdebug-proxy.NOTICE: [Proxy][Xdebug] Listening for new connections on '127.0.0.1:9002'... array ( ) array ( )

So by default proxy listens 127.0.0.1:9001 for ide registration connections and 127.0.0.1:9002 for xdebug connections, use 127.0.0.1:9000 as default IDE and predefined IDE with key idekey.

Config

If you want to configure listening ports, etc., you can use custom config path. Just copy config directory to your custom path:

cp -r /path/to/php-xdebug-proxy/config /your/custom/path

There are 3 files:

• config.php:

  <?php
  return [
      'xdebugServer' => [
          // xdebug proxy server host:port
          'listen' => '127.0.0.1:9002',
      ],
      'ideServer' => [
          // if proxy can't find ide, then it uses default ide,
          // pass empty string if you want to disable default ide
          // defaultIde is useful when there is only one user for proxy
          'defaultIde' => '127.0.0.1:9000',
          // predefined ide list in format 'idekey' => 'host:port',
          // pass empty array if you don't need predefined ide list
          // predefinedIdeList is useful when proxy's users aren't changed often,
          // so they don't need to register in proxy each proxy restart
          'predefinedIdeList' => [
              'idekey' => '127.0.0.1:9000',
          ],
      ],
      'ideRegistrationServer' => [
          // host:port for register ide in proxy
          // pass empty string if you want to disable ide registration
          'listen' => '127.0.0.1:9001',
      ],
  ];

• logger.php: you can customize a logger, the file should return an object, which is instance of \Psr\Log\LoggerInterface;
• factory.php: you can customize classes, which are used in proxy, file should return object, which is instanceof Factory\Factory.

Then change configs and run:

bin/xdebug-proxy --configs=/your/custom/path/config

Extending

As mentioned above you can customize classes using your custom factory, which implements Factory\Factory. By default Factory\DefaultFactory factory is used.

The most powerful are the request preparers. You can override Factory\DefaultFactory::createRequestPreparers(). It should return an array of objects which implement RequestPreparer\RequestPreparer interface.

Request preparers will be called:

• on request to ide from first to last
• on request to xdebug from last to first

You can use request preparer for example for changing path to files (in break points and execution files).

Good example of the request preparer is RequestPreparer\SoftMocksRequestPreparer. You can see its usage in Factory\SoftMocksFactory.

Using with soft-mocks

For soft-mocks you can use softMocksConfig config directory:

bin/xdebug-proxy --configs=/path/to/php-xdebug-proxy/softMocksConfig

If you you want to provide path to custom soft-mocks init script, then copy softMocksConfig and change config.php:

...
    'softMocks' => [
        // if empty string, then vendor/badoo/soft-mocks/src/init_with_composer.php is used
        'initScript' => '/your/custom/init-script.php',
    ],
...

For more information see doc in soft-mocks project.
