 First refer to [[vms:webdev:apache#make_sure_everything_is_running as_expected|this section of the wiki]] to have PHP output it's configuration summary, and copy/paste it in the above mentioned [[http://xdebug.org/wizard.php|XDebug wizard]].

 To make sure XDebug is working, you can check the phpinfo(); output that you initialy used to feed the wizard. Reloading the page should now contain an "xdebug section".
+===== Configuring Apache fcgid Timeout =====
+Running Xdebug will often suspend your scripts execution for a longer period than the default, 40 sec, mod_fcgid read data timeout. That will result in your browser throwing a "500 - Internal Server Error" before you complete the debugging session, also suspending debugging possibilities.
+We'll increase the timeout limits by editing the following configuration parameter in **/etc/apache2/mods-available/fcgid.conf**
+<code>
+> nano /etc/apache2/mods-available/fcgid.conf
+ADD:
+...
+  FcgidConnectTimeout 20
+  FcgidIOTimeout 300
+...
+</code>
+Don't forget to restart the apache2 service to apply those changes:
+<code>
+> service apache2 restart
+</code>

+Make sure the Xdebug port is set to the same port as specified in your php.ini file (default: 9000).

+===== Setting up Xdebug’s remote debug with Atom (1.12.5) =====
+=== Install Atom Package php-debug (0.2.4) ===
+  * Open the Atom editor and open settings: Edit > Preferences (ctrl-,)
+  * Select "Install" from the left menu
+  * Type "php-debug" in Search packages field, then //return// to launch the search
+  * php-debug should appear on top of the list, click the "Install" button
+  * Read the README that is displayed
+For php-debug to be able to give accurate feedback in Atom, you'll need to set the **Path Maps** in the php-debug settings.\\
+Note that you only need to specify the mapping from your server's root directory to your corresponding local root, your projects sub directories can be inferred from this information.
+=== Configure Xdebug ===
+You have to configure Xdebug for the specific PHP version that you want to debug with, so you'll have to adapt the following with the corresponding location.
+In this case we'll configure our PHP version 5.6.27 to debug from Atom. First we'll edit our ''php.ini'' file:
+<code>
+> sudo nano /opt/phpfarm/inst/php-5.6.27/lib/php.ini
+PASTE AT EOF (removing any existing [xdebug] lines):
+[xdebug]
+zend_extension = "/opt/phpfarm/inst/php-5.6.27/lib/php/extensions/no-debug-non-zts-20131226/xdebug.so"
+xdebug.profiler_output_dir = "/tmp/xdebug"
+xdebug.trace_output_dir = "/tmp/xdebug"
+; additional settings (atom)
+xdebug.remote_enable=1
+xdebug.remote_handler=dbgp
+xdebug.remote_mode=req
+xdebug.remote_host=172.20.20.1
+xdebug.remote_port=9000
+xdebug.idekey=xdebug.atom
+xdebug.remote_autostart=true
+xdebug.collect_params=4
+xdebug.collect_vars=on
+xdebug.show_local_vars=on
+> sudo service apache2 restart
+</code>
+To make sure those values have been taken into account, load the phpinfo page created earlier and check the //**xdebug**// section to make sure the displayed values are in concordance with the ones you've introduced in the ''php.ini'' file.
+=== Remote IP Address ===
+The ''xdebug.remote_host'' IP address should be your workstation's IP. In this example we are using a virtualbox VM as development server. In this case, to find out what IP address to use, issue the ''ip a'' command from your workstation's command line and look for the ''inet'' value of the ''vboxnet0:'' interface.
+In case you're using Xdebug > 2.1 and your workstation's IP address can vary, you could try to use ''xdebug.remote_connect_back=true'' instead of the ''xdebug.remote_host'' value. In this case, Xdebug will try to use the $_SERVER['HTTP_X_FORWARDED_FOR'] and $_SERVER['REMOTE_ADDR'] variables to find out which IP address to use. In this case you should **not** set the ''xdebug.remote_host'' parameter in your php.ini.
+=== Xdebug autostart ===
+With ''xdebug.remote_autostart=true'', PHP will **connect to your editor for every script it executes**, which brings quite an overhead to all your PHP executions on the server. The alternative is to use ''xdebug.remote_autostart=false'', and install an Xdebug helper extension for your browser of choice, such as:
+  * [[https://addons.mozilla.org/en-US/firefox/addon/the-easiest-xdebug/|The easiest Xdebug for Mozilla Firefox]]
+  * [[https://chrome.google.com/webstore/detail/xdebug-helper|Xdebug Helper for Google Chrome]]
+These browser extensions will give you a button within your browser to enable/disable Xdebug.\\
+In case you notice, in the xdebug table of the phpinfo page, that the **IDE Key** value (right under the version number) **is different from the xdebug.idekey** value set in the php.ini file, verify the parameters of your browser's xdebug extension.
+=== All Xdebug settings ===
+You can learn more about all possible Xdebug settings in the [[https://xdebug.org/docs/all_settings|Xdebug documentation]].
