无法在Ubuntu 16.04上加载PHP7 mongodb驱动程序

Question

I have Ubuntu 16.04 and only pre-installed PHP7 on it. So, I have normally installed and started MongoDB 3.2, but cannot run php driver.

pecl install mongodb

works correct and currently shows that mongodb 1.2.0 driver is already installed. I have of course added " extension=mongodb.so " to php.ini file. So, php -v prints an error:

PHP Warning:  PHP Startup: Unable to load dynamic library '/usr/lib/php/20151012/mongodb.so' - /usr/lib/php/20151012/mongodb.so: undefined symbol: php_json_serializable_ce in Unknown on line 0

I read all SO answers about it, tried to google any information, but still no result. All github opened issues with some kind of this type of error are also contain no answer.

So, how to make it work? Thank you in advance.
