IntelliJ IDEA 14.0.0 Web Help

Configuring Zend Debugger

Configuring the Zend Debugger tool involves:

Downloading and installing Zend Debugger

  1. Download the Zend Debugger package which corresponds to your operating system.
  2. Locate the ZendDebugger.so (Unix) or ZendDebugger.dll (Windows) file in the directory which corresponds to your version of PHP (e.g. 4.3.x, 4.4.x, 5.0.x, 5.1.x, 5.2.x, 5.3.x, 5.4.x).
  3. Copy the file to your Web server in a location that is accessible by the Web server.

Enabling Zend Debugger integration with the PHP engine

  1. Locate and open the active php.ini file.
  2. Locate or create the [Zend] section.
  3. To load the Zend Debugger extension, add one of the following lines inside the [Zend] section depending on your operating system:
    • Linux and OS X:
      zend_extension=<full_path_to_ZendDebugger.so>
    • Windows:
      zend_extension_ts=<full_path_to_ZendDebugger.dll>
    • Windows non-thread safe:
      zend_extension=<full_path_to_ZendDebugger.dll>
  4. To enable access to Zend Debugger from PhpStorm, add the following lines:
    zend_extension=<full_path_to_zend_debugger_extension> zend_debugger.allow_hosts=127.0.0.1 zend_debugger.expose_remotely=allowed_host zend_debugger.tunnel_min_port=<any integer value above 1024> zend_debugger.tunnel_max_port=<any integer value below 65535>

    The value of the zend_debugger.allow_hosts parameter is the IPs of your machine to connect to the server debugger. It could be a comma-separated list of IPs in the format X.X.X.X (for example, 192.168.0.6).

  5. Restart your Web server.
  6. To check that the Zend Debugger has been installed and configured correctly, create a file with the following contents:
    <?php phpinfo(); ?>
    Open the page that corresponds to the file in the browser. The output should contain a Zend Debugger section.

Integrating Zend Debugger with IntelliJ IDEA

  1. Open the Project Settings and click PHP.
  2. On the PHP page that opens, click the Browse button browseButton next to the Interpreter drop-down list.
  3. In the Interpreter dialog box that opens, choose Zend Debugger from the Debugger drop-down list.
  4. Define the Zend Debugger behaviour. Click Debug under the PHP node. On the Debug page that opens, specify the following settings in the Zend Debugger area:
    • In the Debug Port text box, appoint the port for IntelliJ IDEA to communicate with the tool through. Type the port number within the tunnel specified in the php.ini file through zend_debugger.tunnel_min_port and zend_debugger.tunnel_max_port. For details, see http://files.zend.com/help/previous-version/Zend-Server-4-Community-Edition/zenddebugger.html
    • To have IntelliJ IDEA accept any incoming connections from Zend Debugger engines through the port specified in the Debug port text box, select the Can accept external connections check box.
    • To use a debugger toolbar in the browser, specify the port through which the debugger settings are passed to the browser in the Settings broadcasting port text box.
  5. To have Zend Debugger stop as soon as connection between it and IntelliJ IDEA is established (instead of running automatically until the first breakpoint is reached), turn on the Run | Break at first line in PHP scripts option on the main menu.
