PHP和Mongo的多个版本

I have some version php and I need install mongo for 5.6 version. Early I have mongo for 5.5 version and now intsall

ivan@ivan-PC:/usr/lib/php$ sudo pecl install mongodb
pecl/mongodb is already installed and is the same as the released version 1.1.9
install failed

sudo pecl install mongo
pecl/mongo is already installed and is the same as the released version 1.6.14

install failed

and when I check php -m I dont see mongo and in phpinfo not find mongo. Try like this

phpenmod -v php5.6 mongodb

but inthis way

/etc/php/5.6/mods-available/

have

mongo.ini

whe run php -m not have mongo module

sudo pecl info mongo
About pecl.php.net/mongo-1.6.14

But still not mongo for my version php. How to right enable mongo for another php version ?

Switch to required php version with

sudo update-alternatives --config=php
sudo update-alternatives --config=php-config
sudo update-alternatives --config=phpize

Just run install with force flag

sudo pecl install -f mongodb
