+slug: /developers/xdebug/xdebug-on-php-wasm
+description: Debug PHP in WebAssembly with Xdebug using VS Code, Cursor, or PhpStorm. Set breakpoints and inspect variables.
+---
+
+# Debugging with Xdebug in PHP WASM CLI
+
+The **php-wasm CLI** supports Xdebug, allowing developers to debug PHP code running within the WebAssembly environment. Set breakpoints, step through code execution, inspect variables, and modify them at runtime.
+
+PHP WASM CLI debugs any PHP code—you don't need WordPress. This works for all PHP developers.
+
+## Prerequisites
+
+You need an IDE that supports Xdebug and its configuration file.
+
+-   **A configuration file:** For example, `.vscode/launch.json` for VS Code-based IDEs and `.idea/workspace.xml` for PhpStorm
+-   **VS Code / Cursor:** We recommend the official [PHP Debug extension](https://marketplace.visualstudio.com/items?itemName=xdebug.php-debug).
+-   **PhpStorm:** supports Xdebug natively.
+
+## Usage Guide
+
+### 1. Create or select your PHP file
+
+This example demonstrates Xdebug debugging:
+
+```PHP
+<?php
+
+$test = 42; // Set a breakpoint on this line
+
+echo "Output!\n";
+
+function test( $output ) {
+    echo "Hello Xdebug World!\n" . $output . "\n";
+}
+
+test($test);
+```
+
+### 2. Configure your IDE
+
+Before running the script, prepare your IDE to listen for the Xdebug connection.
+
+#### **VS Code / Cursor Instructions**
+
+1.  Ensure you have installed the **PHP Debug** extension.
+2.  Open the **Run and Debug** panel on the left sidebar.
+3.  Select **"PHP.wasm CLI - Listen for Xdebug"** from the configuration dropdown.
+4.  Click the **Start Debugging** (play button) icon.
+
+#### **PhpStorm Instructions**
+
+1.  Choose the **"PHP.wasm CLI - Listen for Xdebug"** debug configuration in the toolbar.
+2.  Click the **Debug** button (bug icon).
+
+### 3. Set a Breakpoint
+
+Open your target file (e.g., `src/test.php`) and set a breakpoint on the desired line.
+
+### 4. Run the CLI Command
+
+Execute the script using the CLI. You must include the `--xdebug` flag to enable the connection.
+
+```bash
+npx @php-wasm/cli@latest --xdebug src/test.php
+```
+
+> **Note:** Start your IDE's debug listener before running this command. Otherwise, Xdebug waits indefinitely for the connection.

+
+If you don't have the IDE set up, you can use the experimental flag `--experimental-unsafe-ide-integration`, passing the IDE that you would like to set, `vscode` or `phpstorm`. The flag is also set as unsafe because it can overwrite the previous configuration of your IDE.
+
+```bash
+npx @php-wasm/cli@latest --xdebug --experimental-unsafe-ide-integration=phpstorm src/test.php
+```
+
+### 5. Start Debugging
+
+Once the command is running and your IDE is listening:
+
+1.  The execution will pause at your defined breakpoint.
+2.  If no breakpoint is set, execution will automatically break on the first line.
+3.  You can now inspect variables, call stacks, and step through the code.
+
+**Example Output:**
+
+```text
+Output!
+Hello Xdebug World!
+42
+```

+
+| Flag                                    | Description                                                               |
+| :-------------------------------------- | :------------------------------------------------------------------------ |
+| `--xdebug`                              | Enables the Xdebug extension within the WASM environment.                 |
+| `--experimental-unsafe-ide-integration` | Allows the WASM instance to communicate with the IDE on the host machine. |
