PHP 7 with Doctrine MongoDB ODM
I have a Symfony 2 application that is using Doctrine MongoDB ODM and I'm trying to get this running with PHP 7.
I have installed PHP 7 successfully but installing dependencies through Composer is giving me grief with the following error:
doctrine/mongodb 1.0.x-dev requires ext-mongo >=1.2.12,<1.7-dev -> the requested PHP extension mongo is missing from your system.
I managed to install the PHP 7 mongo extension through apt:
apt-get install php7.0-mongo
Just to be sure, I have also installed the mongodb extension through PECL:
sudo apt-get install -y php-pear php7.0-dev libcurl3-openssl-dev
sudo pecl install mongodb
However, I'm still get the error that the mongo extension cannot be found. There seems to be a version discrepancy in that ext-mongo >=1.2.12 is required but only 1.1.6 was installed::
$ php -i | grep mongo
/etc/php/7.0/cli/conf.d/20-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 is the correct way to install the mongo extension required by Doctrine ODM for PHP 7?
Answer
On PHP7 you cannot install mongo extension. What you can do, is to install https://github.com/alcaeus/mongo-php-adapter first, then install doctrine.
composer require alcaeus/mongo-php-adapter
