This section provides a handful selection of tutorials that will help you get started with PHP debugging in PhpStorm.
Quick Start
Something that’s fairly easy to do with PhpStorm! Whether it’s a full web application, some library code or just a unit test, profiling allows us to gather program execution statistics. During this webinar we explore the integration between Zend Server’s Z-Ray and the PhpStorm IDE, from debugging and profiling your applications seamlessly to preparing deployment packages in the IDE to be deployed to Zend Server, and more. This webinar is geared towards developers of different proficiency. It also features live Q&A session. Mar 08, 2021 PhpStorm provides visual representation of profiling data generated by Xdebug. You can select several snapshots at a time and collect the aggregated profiling information. Before profiling with Xdebug, download, install and configure the components of the PHP development environment.

Hello everyone, i've got some problems with the xdebug profiler. Actually i don't know what i must do to change the settings to enable the profiling.
Before proceeding with any of the debugging scenarios, you need to choose a debugging engine and install it in your PHP environment. These tutorials will guide you through the installation process:
PHPStorm is a great coding environment for those who work with PHP frameworks like WordPress, Drupal, Magento, and others. It has an interface that is both great to look at and easy-to-use. It’s compatible with Mac, Windows, and Linux and supports a number of different front-end programming languages like HTML5, CSS, JavaScript.
With the debugging engine installed, you can start debugging by following the zero-configuration debugging approach:
Choose and install the browser extension suitable for your browser.
On the PhpStorm toolbar, toggle to start listening for incoming PHP debug connections, or choose Run | Start Listening for PHP Debug Connections from the main menu.
Set a breakpoint in your code. Breakpoints can be set in the PHP context inside PHP, HTML, TWIG, BLADE, and files of other types. Line breakpoints can be set only on executable lines, but not on comments, declarations, or empty lines. For details on getting started with Twig and Blade debugging, refer to Debug Twig templates and Debug Blade templates.
Start the debugging session in the browser using the installed browser extension.
During a debugging session, examine the program state: see variable values, evaluate expressions, step through the program, and so on.
See Zero-configuration debugging for the detailed step-by-step instructions, and Advanced debugging scenarios for more debugging scenarios.
Debugging a PHP web application
Depending on your environment, you can debug your PHP Web application locally or remotely.
| Local debugging | Remote debugging |
|---|---|
| The debugging engine and PhpStorm are running on the same machine. | The debugging engine is running on a remote environment (for example, a remote server or a virtual machine). |
| Follow the Zero-configuration debugging procedure. |

To test direct connection, run the telnet host 9000 (for Xdebug) or the telnet host 10137 (for Zend Debugger) command on the remote server and ensure that connection is established. Here, host is the IP address of the local machine PhpStorm is running on.
To check for opened inbound ports, you can use canyouseeme.org or a similar service.
Debugging a PHP CLI script
Depending on your environment, you can debug your PHP CLI script locally or remotely.
| Local debugging | Remote debugging |
|---|---|
| The debugging engine and PhpStorm are running on the same machine. | The debugging engine is running on a remote environment (for example, a remote server or a virtual machine). |
| Follow the Debug a PHP CLI script procedure. |
|
Besides running an entire application, you may want to run a PHPUnit or Behat test that covers a specific class, function or scenario, with the debugging engine attached. To learn how to do it, follow the Create a test configuration for a specific target procedure.

Troubleshooting
When using Xdebug or Zend Debugger with PhpStorm, some misconfiguration can prevent the debugger from working. In the Troubleshooting guide, you will find the description of some common issues and learn how to troubleshoot them.
