Composer will not work with current settings

Question

The PHP exe file you specified did not run correctly:

C:\xampp\php\php.exe

The php.ini used by your command-line PHP is: C:\xampp\php\php.ini

Program Output:

Warning: PHP Startup: mongo: Unable to initialize module
Module compiled with module API=20121212
PHP compiled with module API=20131226
These options need to match in Unknown on line 0

Update

Composer can't find mongodb extension in php

C:\wamp\www\phpmongodb>composer require "mongodb/mongodb=^1.0.0"
You are running composer with xdebug enabled. This has a major impact on runtime performance. See https://getcomposer.org/xdebug
./composer.json has been updated
Loading composer repositories with package information
Updating dependencies (including require-dev)
Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - mongodb/mongodb 1.0.2 requires ext-mongodb ^1.1.0 -> the requested PHP extension mongodb is missing from your system.
    - mongodb/mongodb 1.0.2 requires ext-mongodb ^1.1.0 -> the requested PHP extension mongodb is missing from your system.
    - mongodb/mongodb 1.0.1 requires ext-mongodb ^1.1.0 -> the requested PHP extension mongodb is missing from your system.
    - mongodb/mongodb 1.0.0 requires ext-mongodb ^1.1.0 -> the requested PHP extension mongodb is missing from your system.
    - mongodb/mongodb 1.0.2 requires ext-mongodb ^1.1.0 -> the requested PHP extension mongodb is missing from your system.
    - Installation request for mongodb/mongodb ^1.0.0 -> satisfiable by mongodb/mongodb[1.0.0, 1.0.1, 1.0.2].

  To enable extensions, verify that they are enabled in those .ini files:
    - C:\wamp\bin\php\php5.5.12\php.ini
  You can also run `php --ini` inside terminal to see which files are used by PHP in CLI mode.

Installation failed, reverting ./composer.json to its original content.

Problem

This is a PHP Extension installation issue.

The error means, that the PHP Extension mongo doesn't fit your PHP version. It's incompatible.

Solution

The solution is to check your PHP version with php -v and then install the matching "mongo" extension.

PHP Extension Mongo https://pecl.php.net/package/mongo + http://php.net/mongo/

Reminder: The PHP extension Mongo is deprecated. The replacement is MongoDB https://pecl.php.net/package/mongodb + http://php.net/mongodb/
Another simple solution is to delete the php_mongo.dll from the extension folder and remove it from php.ini to allow a proper PHP start.

After that, Composer and all other PHP CLI applications should work normally.

Answer for the updated question

the requested PHP extension mongodb is missing from your system

Now, mongodb is missing:

Download
drop php_mongodb.dll into the extension folder
edit your php.ini to include the extension.
