How to import third-party libraries in ThinkPHP
Third-party class libraries Third-party class libraries refer to other class libraries besides the ThinkPHP framework and application project class libraries. They are generally provided by third-party systems or products, such as class libraries of Smarty, Zend and other systems. For the class libraries imported earlier using automatic loading or the import method, the ThinkPHP convention is to use .class.php as the suffix. Non-such suffixes need to be controlled through the import parameters. But for the third type of library, since there is no such agreement, its suffix can only be considered to be php.
