You can also click directly into the Value column and manually change variable values. Setting watches destabilizes XDebug and is not recommended. Watches are disabled by default.

Debugging in PHP

However if you want to set watches, see Using Additional Watches. The Call Stack window lists the sequence of calls made during execution. When the debugger is suspended, the Call Stack window shows the sequence of function calls i. On initial suspension, the top-most stack frame is selected automatically. Double-click on a function call in the window to go to that line in the editor. If the call is made to a PHP class, the Navigator window will also go to that line when you double-click the call.

You can double-click on a call stack frame to select it, then explore any variable or expression values for that frame in the Variables and Watches windows. The Threads window indicates which PHP script is currently active and whether it is suspended at a breakpoint or running. If the script is running, you need to go to the browser window and interact with the script. The Sources window displays all the files and scripts loaded for the debugging session.

Documentation

The Sources window does not currently function for PHP projects. From the Breakpoints window you can enable or disable breakpoints in the Context window. You can also create breakpoint groups. You can define an additional watch expression to follow up your program execution. This may help you catch an error.

Installing Xdebug

It is possible to debug both scripts and web pages, and web pages can be debugged either locally or remotely. For Remote Debugging, unfortunately the debugged php file on the remote server isn't the same as the file opened in NetBeans IDE running on a local machine.

Debugging PHP with Xdebug Intro

Debugger support in NetBeans must thus be able to map server paths to local paths. However, due to many complications, path mapping cannot be resolved automatically for every individual scenario. Therefore, starting in NetBeans 6. You can also specify the proxy server, if any, and the URL at which the debugging session starts. If you do not specify this URL, debugging starts at your index file. To send comments and suggestions, get support, and keep informed on the latest developments on the NetBeans IDE PHP development features, join the users php.

How to Use Xdebug for Advanced PHP Debugging

Practically, this means the following workflow: Set a breakpoint at each line where PHP source code execution should pause. Start a debugging session. When a line with a breakpoint is reached, execute the script one line after another by pressing F7 and F8. Monitor the state of the application in the debugger windows.

Close the debugging session. Another great use of Xdebug is proactively during development itself, instead of reacting to issues with existing code. Do you work with a different local environment and need some guidance? Let us know in the comments. PhpStorm has an awesome integration with Xdebug and is simple to set up. This is done by setting breakpoints at certain lines of your code and telling PhpStorm to listen for incoming connections. When PHP executes a line that has a breakpoint on it, Xdebug will step in and pause execution allowing you to gain valuable insight to all that is happening during execution:.

The sidebar of the debug panel has various buttons for controlling the execution of the code. Here they are top down as they appear in the screenshot:. The top bar of the panel controls how the debugger traverses the code so you can inspect different parts of the codebase:. Breakpoints are added by clicking in the left-hand gutter of the code, along the line you want at which you want to break. PhpStorm also allows you to set conditional breakpoints, where you add PHP logic to control when a breakpoint actually fires:.

    5. When troubleshooting, it is often helpful to inspect and watch the value of a variable all the way through the execution of a request to see when it changes. Enabling Xdebug gives you, by default, an extended stack trace for any errors, notices or warnings that are written to the PHP log:. The extended stack trace is helpful on its own, but, coupled with PhpStorm, you get a dynamic view of the trace when debugging.

    This dynamic view gives you an interactive history of what code has been executed up to the breakpoint or current point of the execution:. Here are some advanced ways you can use Xdebug to improve your development workflows. But Xdebug also profiles for you and PhpStorm can interpret the results, which is great as it means you never have to leave PhpStorm!
