PHP's _ clone () method is used to perform a shortest copy on an object instance. The basic value type in the object is copying the data transfer value, and the object type member variable in the object, if you do not overwrite the _ clone method

Loading third-party classes with reflection is useful in: Configure the class to be loaded using XML or other configuration files to separate the class from the system source code. Performs a class check on the loaded class. The loaded class

First, clarify the PHP output sequence 1. Open the PHP output cache: ECHO, print-> PHP output_buffring-> server buffering-> browser buffering-> Browser display 2. php output cache not enabled: ECHO, print-> server buffering-> browser buffering->
