Installing the MongoDB PHP Extension on Windows

Precompiled binaries are attached to the project's » Github releases. Archives are published for various combinations of PHP version, thread safety (TS or NTS), and architecture (x86 or x64). Determining the correct archive for the PHP environment and extract the php_mongodb.dll file to the extension directory ("ext" by default).

Add the following line to the php.ini file for each environment that will need to use the extension:


Failure to select the correct binary will result in an error when attempting to load the extension DLL at runtime:

PHP Warning:  PHP Startup: Unable to load dynamic library 'mongodb'

Ensure that the downloaded DLL corresponds to the following PHP runtime properties:

In addition to the aforementioned constants, these properties can also be inferred from phpinfo(). If a system has multiple PHP runtimes installed, double-check that the phpinfo() output is for the correct environment.

Note: Additional DLL dependencies for Windows Users

In order for this extension to work, there are DLL files that must be available to the Windows system PATH. For information on how to do this, see the FAQ entitled "How do I add my PHP directory to the PATH on Windows". Although copying DLL files from the PHP folder into the Windows system directory also works (because the system directory is by default in the system's PATH), this is not recommended. This extension requires the following files to be in the PATH: libsasl.dll
