PHP Reflection API Sample Sharing _php Tips

This example for you to share the PHP reflection api--using reflection technology to implement the plug-in system framework for your reference, the specific content as follows

<?php/** * @name PHP Reflection api--The plug-in system architecture implemented using reflection technology * */** * First invoke the Findplugins method to obtain a method to obtain the class * that implements the interface and then call the Reflection class * @param $meth Od method name * @param $interfaceName Interface Name * @return The return result corresponding to the array method name * * Function Compute ($method, $interfaceName) {$findPl
