Building the MongoDB PHP Driver from source

For driver developers and people interested in the latest bugfixes, you can compile the driver from the latest source code on » Github. Run the following commands to clone and build the project: 

$ git clone https://github.com/mongodb/mongo-php-driver.git
$ cd mongo-php-driver
$ git submodule update --init
$ phpize
$ ./configure
$ make all
$ sudo make install

If your system has multiple version of PHP installed (e.g. macOS default and » XAMPP), note that each version of PHP has its own phpize command and php.ini file.

By default, the driver will use bundled versions of » libbson, » libmongoc, and » libmongocrypt and attempt to configure them on its own. If these libraries are already installed as system libraries, you can instruct the driver to utilize them by specifying --with-libbson=yes --with--libmongoc=yes as arguments to configure. Starting with version 1.7.0 of the extension, these arguments are deprecated and you should use --with-mongodb-system-libs=yes instead.

For a complete list of configure options, run configure --help.

When using bundled versions of libbson and libmongoc, the driver will also attempt to select an SSL library according to the --with-mongodb-ssl option for configure. The default value is --with-mongodb-ssl=auto, which will search for Secure Transport (macOS only), OpenSSL, and LibreSSL, in that order. Additionally, you may specify openssl, libressl, or darwin to force selection of a particular library, respectively.

Note:

If the build process fails to find an SSL library, check that the development packages (e.g. libssl-dev) and » pkg-config are both installed.

When using Homebrew on macOS, it is common for a system to have multiple versions of OpenSSL installed. To ensure that the desired version of OpenSSL is selected, the PKG_CONFIG_PATH environment variable may be used to control the search path for pkg-config. If pkg-config is not used, configure also supports a --with-openssl-dir=DIR argument, which can be used to specify a manual search path (for OpenSSL only).

The final build step, make install, will report where mongodb.so has been installed, similar to: 

Installing shared extensions:     /usr/lib/php/extensions/debug-non-zts-20151012/

Ensure that the extension_dir option in php.ini points to the directory where mongodb.so was installed. You can query for the option by running: 

$ php -i | grep extension_dir
  extension_dir => /usr/lib/php/extensions/debug-non-zts-20151012 =>
                   /usr/lib/php/extensions/debug-non-zts-20151012

If the directories differ, either change extension_dir in php.ini or manually move mongodb.so to the correct directory.

Finally, add the following line to your php.ini file: 

extension=mongodb.so

After installing mongodb, in terminal there are couple of error ex.

PHP Warning:  PHP Startup: Unable to load dynamic library 'mongodb.so' (tried: C:\xampp\php\ext\mongodb.so (The specified module could not be found.), C:\xampp\php\ext\php_mongodb.so.dll (The specified module could not be found.)) in Unknown on line 0

Warning: PHP Startup: Unable to load dynamic library 'mongodb.so' (tried: C:\xampp\php\ext\mongodb.so (The specified module could not be found.), C:\xampp\php\ext\php_mongodb.so.dll (The specified module could not be found.)) in Unknown on line 0

Solution:
1. If you include mongodb extension in php.ini file first remove that
2. Goto your php path inside Xampp and create an file called mongodb.ini and pest this below line, see ss - https://prnt.sc/ubr7ii
code extension=mongodb.so

This solution works in windows 10, php 7.4 version

You think this is to complicated? You use Ubuntu 14 or 16? use this:

sudo apt-get install php-mongodb

This installs everything you need to use MongoDB inside PHP.

Don't stop using MongoDB, is the best that will happen to you.

You're Welcome.

a) If your git version is not recent enough, as can happen e.g. on Ubuntu 12.04 LTS, git submodule --init won't exist
In that case use:

    git submodule init
    git submodule update

b) make install does not create a mongodb.conf configuration file to support the debian/ubuntu PHP versions phpenmod/phpdismod commands. To have them work:

- do not add the extension=mongodb.so line to php.ini
- add it to a mongodb.ini file in the PHP mods-available directory
- the commands will then work for this extension

c) if you have multiple versions of PHP on a system such as b), the phpenmod/phpdismod commands may fail if the extension is not built for the default PHP CLI version. To have it be enabled for a specific version, use the -v argument, like

    phpenmod -v php7.1 mongodb
