php70-mongo install doctrine/mongodb-odm fails

I try to install doctrine/mongodb-odm[1.0.5] over composer but drops me

Problem 1
- doctrine/mongodb 1.3.0 requires ext-mongo ^1.5 -> the requested PHP extension mongo is missing from your system.
- doctrine/mongodb 1.2.2 requires ext-mongo ^1.2.12 -> the requested PHP extension mongo is missing from your system.
- doctrine/mongodb 1.2.1 requires ext-mongo ^1.2.12 -> the requested PHP extension mongo is missing from your system.
- doctrine/mongodb 1.2.0 requires ext-mongo ^1.2.12 -> the requested PHP extension mongo is missing from your system.
- doctrine/mongodb-odm 1.0.5 requires doctrine/mongodb ~1.2 -> satisfiable by doctrine/mongodb[1.2.0, 1.2.1, 1.2.2, 1.3.0].
- Installation request for doctrine/mongodb-odm ~1.0.5 -> satisfiable by doctrine/mongodb-odm[1.0.5].


mongo extension is already installed

php -i | grep mongo

/usr/local/etc/php/7.0/conf.d/ext-mongodb.ini
mongodb
mongodb support => enabled
mongodb version => 1.1.6
mongodb stability => stable
libmongoc version => 1.3.5
mongodb.debug => no value => no value


what went wrong in this case?

PHP has 2 extensions for MongoDB:

1. The legacy one found at

2. The current one

In case of "doctrine/mongodb-odm" it expects to find the legacy one "mongo" but what you have installed is the newer one "mongodb".

In order to use the legacy extension you need to use php <= 5.6, for php 7 only mongodb is available.

On PHP7 you have `mongodb` extension as @xaben mentioned. You can use this with doctrine until it support `mongodb` but by installing additional library

First install via composer:

composer require alcaeus/mongo-php-adapter

and later install doctrine. It's works very well in my case.

I had the problem , but install and config symfony 3.1 with php 5.6 and mysql , After need installer mongodb, so udpate 7.1

problem composer.json :

"config": {
"platform": {"php": "5.6"}
}

Change:

"config": {
"platform": {"php": "7.1"}
}
