rt, I want to write a crawler now, which requires some complex database operations (subqueries, seven or eight table related connections, and even some statistical functions and logic such as if exist). What is the best performance? Is it an ORM component that has high performance, elegant code and more complete functions?

Recommended: laravel eloquent
You can also find the ORM you need in other frameworks, such as yii
or something.
Or Doctrine, Symfony uses this ORM.
