PHP 7.1 built-in executables (Windows only)

  • The PHP 7.1 built-in executables require the Visual C++ Redistributable for Visual Studio 2015 (x86 variant) to be installed in the operating system. The installer of Zend Studio 13 and later installs it automatically, but users upgrading from earlier Zend Studio version must install it manually from here:

Apigility integration requirements

  • Internet Explorer >=10 is required on Windows for the Apigility Editor to render correctly.

Code Trace requirements

  • Flash Player must be installed in the operating system.

Known Issues

  • Update to Zend Studio 13 or newer from older versions is not supported on Mac OS X. New installation of Zend Studio 13 or newer is required. If an update is attempted, this will corrupt the Zend Studio installation.

  • During update of Studio a security warning about unsigned content may be shown. You can safely ignore this warning and proceed with the upgrade.

  • Z-Ray may not render correctly inside Zend Studio on Windows. A workaround can be applied in one of the following alternative ways:

    • Modify Zend Server configuration to include the "X-UA-Compatible: IE=edge" HTTP header in the response. If Zend Server is running on Apache HTTP Server then:
      • Add the following line in the httpd.conf file:

        Header add X-UA-Compatible "IE=edge"
      • Restart the Apache HTTP Server.

      • Reopen the web browser inside Zend Studio.

    • Modify the application to include "X-UA-Compatible: IE=edge" HTTP header in the response:
      • Add the following line in a suitable place in your PHP code:

        header("X-UA-Compatible: IE=edge");
      • Reopen the web browser inside Zend Studio.

    In Zend Server 8 and later Z-Ray will automatically add the "X-UA-Compatible: IE=edge" HTTP header in the response, so the above workaround will not be required.

  • Zend Debugger PHP extension is not available for PHP builds with Thread Safety enabled. You can find out the status of Thread Safety in your PHP:

    • in phpinfo() output
    • by checking the value of the predefined constant PHP_ZTS ("false" means Non Thread Safe, i.e. supported by Zend Debugger)

    If you use Thread-Safe PHP, consider Xdebug as the alternative.

  • Zend Studio Crashes with Segmentation Fault in KDE 4.11 and newer, see

  • Zend Studio menus do not show or appear only partially in the menu bar of Ubuntu 13.10 and 14.04. The issue is caused by Ubuntu's bug See 

  • To display class inheritance charts in the documentation generated by PHPDocumentor installation of Graphviz is required. Due to compatibility issues, please install 

    • Graphviz version 2.30.1 on Mountain Lion and newer
    • Graphviz version 2.28.0 on Windows and older OS X versions
