Installing ZendPHP on Windows (PowerShell Script)

Important This topic describes the legacy procedure for installing and uninstalling ZendPHP on Windows using a PowerShell script. This installation method is no longer supported. For new installations, use the instructions under Installing ZendPHP on Windows (MSI package) instead.


  • Windows 10 or 11; Windows Server 2019
  • 64-bit architecture
  • Visual C++ 2017 or later runtime (the installer can install this for you)
  • Optional libraries that can be installed using the installer:
    • Management Information Base (MIBS) libraries; required for the SNMP extension
    • Oracle Instant Client libraries; required for the oci8/pdo_oci extensions
    • PostgreSQL client libraries; required for the pgsql/pdo_pgsql extensions

Getting the installer

To get the ZendPHP installer for Windows:

  1. Download ZendPHP for Windows Installer from

  2. Extract the archive ( on your machine. This can generally be done using Windows Explorer or in PowerShell using the command Expand-Archive -DestinationPath {folder}, where {folder} is the location where you would like to extract the contents. The package contains a readme.txt file with instructions and the script zendphp_install.ps1, which is a PowerShell script.

  3. Start PowerShell and navigate to the directory in which you extracted the installer.

  4. Run zendphp_install.ps1 help to get usage details and a full list of options.

Installation notes

  • The installer notifies you if you do not have a compatible Visual C++ runtime. Use the -with-deps vcruntime option to install it.
  • We ship several PECL extensions separate from our standard PHP distribution. These include:
    The installer lets you install one or more of these at any time using the -pecl option (e.g., -pecl xdebug or -pecl memcache,redis). If you want to install these after installing PHP and without updating PHP, you can do so by passing the -deps-only switch.
  • You can enable one or more built-in extensions at installation using the -enable option (e.g., -enable intl or -enable curl,fileinfo). The -enable-all switch enables all built-in extensions.
  • After installing you can use the config sub-command to disable one or more built-in or PECL extensions using the -disable option (e.g., -disable intl or -disable curl,redis). The -disable-all switch disables all extensions.
  • You can install more than one PHP version at a time. By default, the installer installs to C:\zendphp\{version}, where {version} is the PHP minor version (e.g., 7.4, 8.1, and so forth). As such, you can install and configure PECL extensions for each PHP version independently.

Installation examples

To install PHP 8.1, the Visual C++ runtime, the Microsoft SQL Server extension, and enable the curl, openssl, opcache, phar, and xsl extensions you would use:

zendphp_install.ps1 install 8.1 -with-deps vcruntime -pecl sqlsrv -enable curl,openssl,opcache,phar,xsl

To later enable all built-in extensions for 8.1, but disable snmp, shmop, sysvshm, pdo_oci, pdo_pgsql, oci8, and pgsql you would use:

zendphp_install.ps1 config 8.1 -enable-all -disable snmp,shmop,sysvshm,pdo_oci,pdo_pgsql,oci8,pgsql


ZendPHP releases follow community PHP releases within a few days and community PHP releases are generally monthly. You can update your ZendPHP installation using the same command you used to install originally; the only difference is you typically do not need to use the -with-deps or -enable options.

As an example, if you installed PHP 8.1 using the following:

zendphp_install.ps1 install 8.1 -with-deps vcruntime -pecl sqlsrv -enable curl,openssl,opcache,phar,xsl

To update, you would use:

zendphp_install.ps1 install 8.1 -pecl sqlsrv

We recommend passing the -pecl option for any PECL extensions you normally install during updates to ensure you get patched versions.


To remove a single ZendPHP version, delete the directory C:\zendphp\{VERSION}. If you specified a custom directory, replace C:\zendphp with the directory that you provided when calling zendphp_install.ps1 install.

To remove all ZendPHP versions, remove the directory C:\zendphp\, or, If you specified a custom directory when invoking zendphp_install.ps1 install, delete that custom directory.
