Tried using the pecl installation way on the server sudo pecl install mongodb (after doing a sudo apt-get remove mongodb) The installation completed with version 1.3.4 getting installed. I added extension=mongodb.so to my /etc/php/7.0/apache2/php.ini file too. But this doesn't work - 1. php -m didn't have mongodb in the list., 2. Also, running composer update on my php project failed with following output -

Problem 1
    - Installation request for mongodb/mongodb ^1.2 -> satisfiable by mongodb/mongodb[1.2.0].
    - mongodb/mongodb 1.2.0 requires ext-mongodb ^1.3.0 -> the requested PHP extension mongodb has the wrong version (1.1.5) installed.

  To enable extensions, verify that they are enabled in your .ini files:
    - /etc/php/7.0/cli/php.ini
    - /etc/php/7.0/cli/conf.d/10-mysqlnd.ini

  You can also run `php --ini` inside terminal to see which files are used by PHP in CLI mode.

We only maintain the mongodb PECL package, so any questions about OS-specific packages (e.g. apt-get install php-mongodb) should be directed to those maintainers within the OS projects. For instance, PHP packages for Fedora/CentOS and Ubuntu are maintained by Remi and Ondřej Surý, respectively. If possible, you should be using their custom repositories (e.g. Ubuntu PPA) for the most up-to-date releases.

I added extension=mongodb.so to my /etc/php/7.0/apache2/php.ini file too. But this doesn't work - 1. php -m didn't have mongodb in the list., 2. Also, running composer update on my php project failed with following output

You may be forgetting that PHP's CLI environment (i.e. php console command) has its own INI file. If you've only added the driver to the INI file used for Apache's PHP module, it's expected behavior that php -m and Composer (executed in the same CLI environment) would not see it.

PHP Warning: Module 'mongodb' already loaded in Unknown on line 0

Lastly, if you're seeing this warning that means the module is already being loaded somewhere in your PHP configuration. If you've installed it through the OS package manager, that may have already created an included INI for it (e.g. a mongodb.ini file in some conf.d or modules-available directory within PHP's /etc path). Double-check the flow of your PHP INI configuration to ensure that extension=mongodb.so is only processed once.

Added extension=mongodb.so to /etc/php/7.0/cli/php.ini as well. It didn't help.

I ran sudo pecl install mongodb again just to check the output. It was -

PHP Warning:  PHP Startup: Unable to load dynamic library '/usr/lib/php/20151012/mongodb.so' - /usr/lib/php/20151012/mongodb.so: cannot open shared object file: No such file or directory in Unknown on line 0
pecl/mongodb is already installed and is the same as the released version 1.3.4
install failed

php-m output now includes this:

'/usr/lib/php/20151012/mongodb.so' - /usr/lib/php/20151012/mongodb.so: cannot open shared object file: No such file or directory in Unknown on line 0

Double-check the flow of your PHP INI configuration to ensure that extension=mongodb.so is only processed once.

How?

[jmikola]

Added extension=mongodb.so to /etc/php/7.0/cli/php.ini as well. It didn't help.

I ran sudo pecl install mongodb again just to check the output.

When pecl install completes, it reports the location of the compiled mongodb.so file. For instance, on my machine, installing the extension for a local PHP 7.0 environment produces:

Build process completed successfully
Installing '/home/jmikola/bin/php-bin/php-7.0/lib/php/extensions/debug-non-zts-20151012/mongodb.so'
install ok: channel://pecl.php.net/mongodb-1.3.4
configuration option "php_ini" is not set to php.ini location
You should add "extension=mongodb.so" to php.ini

If that install path matches the extension_dir INI setting (it generally should), then you're free to just add extension=mongodb.so to your INI to load the extension. Otherwise, you would need to provide the full path to the extension.

Another item to check is whether you're using the correct pecl command your your PHP environment. pecl config-show should report this. In my case:

 $ which php
/home/jmikola/bin/php-bin/php-7.0/bin/php

$ which pecl
/home/jmikola/bin/php-bin/php-7.0/bin/pecl

$ pecl config-show

Double-check the flow of your PHP INI configuration to ensure that extension=mongodb.so is only processed once.

How?

http://php.net/manual/en/configuration.file.php discusses how PHP searches for the main php.ini file and additional INI files found through "Scan directories" (discussed later in that page). Based on your Composer output:

 To enable extensions, verify that they are enabled in your .ini files:
    - /etc/php/7.0/cli/php.ini
    - /etc/php/7.0/cli/conf.d/...

It looks like /etc/php/7.0/cli/php.ini is the root php.ini file and /etc/php/7.0/cli/conf.d/ is the one scan directory configured for that particular php CLI environment.

@samyak45 Hey, I have been facing the same issue. Were you able to resolve the issue? Could you please help me with the solution to this problem? Thanks, man. :)

In my case
Once I removed sudo apt-get remove php-mongodb
Then install as here
http://php.net/manual/en/mongodb.installation.manual.php

Closing this due to inactivity from the OP. Also, this appeared to be more an issue with mixing up versions of PHP/PECL than an issue with the driver itself (i.e. not a bug).
