Configure the PHP ini file for the xdebug extension. ![]() On RedHat/Fedora/CentOS this may be sudo yum install php53u-pecl-xdebug depending on the repositories and PHP version you are working with. On Debian/Ubuntu this is sudo apt-get install php5-xdebug. Make sure the php5-xdebug package or its equivalent is installed. ![]() Configure PHPStorm on the local machine.Tunnel the remote Xdebug connection to our local machine via ssh.To make this happen we'll do three things: But for now we're going to assume you're trying to debug a machine that is out on the internet that cannot directly access your workstation. If it can you can just configure that in your php.ini or xdebug.ini by setting xdebug.remote_host and you won't have to do all the things we're about to do. Unfortunately with actual server configurations, there is usually no way that an outgoing TCP connection can get to your local workstation. You'll notice that the remote machine is attempting to make a connection to an IDE that is, in our situation, on another machine. When a breakpoint is encountered, Xdebug notifies the IDE on this connection.If the IDE is listening, it gives instructions to Xdebug about breakpoints and such.(If it can't make a connection, it just moves on.) If the PHP session is started with a URL like (or it was earlier, creating a cookie), then Xdebug within the PHP execution will attempt to make a connection to an IDE, which defaults to be at localhost, port 9000.If you have xdebug configured in your PHP configuration (I'll show how later), then when PHP starts executing: The first thing that you absolutely must understand is the sequence of events and how they're initiated. This article will deal directly with Xdebug as the debugging engine on the PHP end and Jetbrains PHPStorm 7.x as the IDE on the workstation side, but these techniques will work for other IDEs like Eclipse or Komodo, and they'll work for the Zend debugging engine as well. When you start trying to control a remote webserver with an IDE running on your local workstation though, it gets even more complicated with the network problems. Learn more about how to set up Xdebug on Dedicated server clusters.Step-debugging is one of the key skills for any developer, and it can be baffling. The request should pause at the break point and allow you to examine the running app. Set a break point in your app, then load a page in your browser. Use the Xdebug helper plugin for your browser to enable debugging. While in listen mode, start the platform xdebug tunnel. In the majority of cases you can just define your app root This lets you define what remote paths on the server correspond to what path on your local machine. The Port should always be 443 and the Debugger set to Xdebug. The Host should be the hostname of the environment on Platform.sh you are debugging. Adding a new server for your Platform.sh environment.Making sure that external connections are allowed.Configuring the Xdebug debug port and making sure it’s set to the expected value ( 9003 as default or the value you chose with -port when opening the tunnel).The common steps for setup usually include: Configure your IDEįollow the instructions for your IDE, such as those for PHPStorm. Their respective plugin pages document how to trigger them when needed. While Xdebug can be triggered from the browser by adding a special query parameter, the preferred way is to use a browser plugin helper. Your requests don’t always reach the same host. Note that because you have several virtual machines running but your tunnel is connected to only one of them, To enable Xdebug, add the following to your app configuration: Xdebug runs as a second PHP-FPM process used only for debugging requests, leaving the normal process unaffected. A Xdebug-compatible IDE installed on your machine.įor setup instructions, consult your IDE’s Xdebug documentation, such as that for PHPStorm.The following table shows the PHP versions where Xdebug is available on Grid environments: 5.4 ![]() So you can’t use it for worker containers.Īlso, note that if you use a custom start command, Note that Xdebug runs only on your app containers. While usually used for local development, it can also be helpful for debugging aberrant behavior on the server.Īs configured on Platform.sh, it avoids any runtime overhead for non-debug requests, even in production, and only allows connections via SSH tunnels to avoid any security issues. Xdebug is a real-time debugger extension for PHP. ![]()
