The project used yii1.1 and php5.5.12 before, but now PHP has been upgraded to 7.1, and the mongodb expansion has also been replaced by php_mongodb-1.2.8.
Then the project reported an error when performing mongodb operations.
Has anyone encountered similar problems, or does anyone know how to solve it? Please give me some advice. Any help is greatly appreciated.
