Before we start debugging, we have to configure a few options so + that PHPEclipse and XDebug know where to find various components.
To begin, we must specify the PHP Interpreter Path. This may + differ depending on your system. For Windows based systems, this is a + path to a file called php.exe. For Linux systems, this is a path to a + file simply called php. For Linux systems, this is often in + /usr/bin/php. To specify the PHP Interpreter, select Preferences from + the Window drop down menu. Open up the PHPEclipse selection and click on + XDebug. In the settings pane on the right that appears, enter your debug + port and the path to your PHP interpreter. The default debug port for + XDebug is 9000, but your system may be setup differently. To verify that + 9000 is the correct port, find a way to access your phpinfo() page and + check the value of xdebug.remote_port. The value of xdebug.remote_port + should match the debug port value.
When you have entered the appropriate values, click on the OK
+ button.
Now that we have configured XDebug, we need to create a debug + configuration. This will tell Eclipse how to start the debugger for your + project. To do this, select 'Open Debug Dialog' from the Run drop down + menu. You will be presented with a list of items which you can debug. + Double click on the entry titled 'PHP XDebug Remote Script'. This will + create a new configuration and allow you to specify the necessary + options. You can provide a name for your debug configuration, and then + you must specify the Ide Identification String. You can select anything + you want for this string. It is recommended to keep it short and + memorable. Ensure that you remember this value for later. In our + example, we will use the string firstproject.
Once you have selected a configuration name and have chosen
+ an identification string, click on the Pathmap tab. In the pathmap tab,
+ you specify how Eclipse translates local path names to remote path
+ names. To map a path, click on the New button to create a new map. If
+ your web server is located on the same system that Eclipse is running
+ on, both of these paths will be the same. In either case, under Local
+ Path enter the path to the root of your project on the machine that
+ Eclipse is running on. In Remote Path, enter the path to the root of
+ your project on the machine the web server is running on.
Once you have specified the proper pathmap, press the Debug
+ button to begin the debugger.
You will notice that in contrast to when we were debugging + locally, remote debugging will not automatically start your script. It + will simply start the debugging and begin listening for connections on + the debugging port. To begin our script, we open it up in a web + browser.
This doesn't actually start debugging your script. There is no + link at this point between your script and the Eclipse debugger. We have + to somehow tell PHP to look for the Eclipse debugger for processing + instructions. To do this, we have to add a variable to the request + string. This variable is called XDEBUG_SESSION_START and its value + should match the Ide Indentification String we specified earlier. In + this case, our new URL will be + http://127.0.0.1/myFirstProject/index.php?XDEBUG_SESSION_START=firstproject.
Once you have added the variable to the URL, press enter to
+ start debugging.
You can now resume the process of debugging as demonstrated in the + local debugging tutorial. The process is the same, except that instead + of the output being displayed in the console it is displayed in the + browser where you loaded your script.
