Xdebug.remote_host type: string, default: localhost When a debug session is triggered, that idekey is read by Xdebug, which is listening to all incoming requests to the server hosting the application, and if it is valid, that in turn will cause Xdebug to send a request to the host server, being PhpStorm. The browser is notified by either having a cookie set (PHP COOKIE), an argument passed as a string in the URL (PHP GET), or an argument posted to the application (PHP POST) the key name is always XDEBUG_SESSION, and for this guide the IDE key (idekey) value is debugit. This is the string that will notify the browser, and thus Xdebug, that a debugging session should begin. The meaning and purpose of these Xdebug configuration settings The path may be different, so verify where the extension is located. The line for enabling it can be included directly above the configuration settings, and will look something like this: zend_extension=/usr/lib64/php/modules/xdebug.so. It is also important to make sure the Xdebug extension is enabled in PHP. The configuration should, at minimum, include the settings just below. However, the server may fail to start if there are duplicate entries, so be sure only one location houses them. Configuration settings can also be written directly in PHP’s /etc/php.ini file. On CentOS, it is usually located at /etc/php.d/xdebug.ini if installed through PECL. The location of the Xdebug configuration file depends on the guest OS. Configuring the guest installation of Xdebug, and what the settings do
This IP is required for the Xdebug configuration file. The IP can also be discovered by running netstat -r from within the guest look at the Gateway value. Upon running vagrant ssh and authenticating into the guest OS, the date of the last login and the IP are displayed. The IP of the host is usually known to the guest, so if Vagrant is configured mostly with defaults, the IP will be something like 10.0.2.2. Vagrant acts as an intermediary between these two communication points.Ī connection to PhpStorm can be established if Xdebug knows the IP address (IP) of the host, where PhpStorm resides. However, in order for the client on the guest (Xdebug) to connect to the server on the host (PhpStorm), it must know where to send its request. This means that Xdebug will connect to Phpstorm whenever the PHP application is accessed, for example, through a browser.
For this use case, Xdebug is the client, and PhpStorm is the server. Connections between Xdebug and PhpStorm are no exception. Generally, the Internet works on a client-server model. The second (2) is the guest: the guest is the virtual OS installed by Vagrant. The first (1) is the host: the host is the main operating system (OS) that Vagrant was installed on. There are two communication points to be aware of when developing in Vagrant. How do Xdebug and PhpStorm communicate through Vagrant? It is also assumed that the application to debug will be accessed through a browser.

It will not explain how to install Vagrant, Xdebug, or any other tool referenced. That location has been moved to “Languages & Frameworks,” and then “PHP.” Who will benefit from reading this guide?Īnyone who has been frustrated and ultimately defeated by attempts to run a successful debugging session through Vagrant will benefit from reading this guide. For example, many parts of this guide mention a “Project Settings ” heading to find the “PHP” subheading this no longer exists in PhpStorm 8. Note that as of PhpStorm 8 some of the preferences have been structured and named differently. The process only varies slightly from the original, so the steps will be included below-instead of in a new article-with a clear distinction between the original steps, which still work very well, and the new ones. As indicated in the original publication, the steps to take advantage of remote interpreters will be delineated. 22, 2015: PhpStorm 8 was released late 2014. When that is available, a new post will be written, with a link to it from this one. It will be significantly easier when PhpStorm 8 is released, due to its ability to define remote interpreters. The process is not as straightforward as it should be, and available documentation has not been clear on this usage. This guide will explain how to configure PhpStorm to use PHP’s Xdebug extension through Vagrant.
