Haven't touched PHP for a long time, even some of the basic things are almost forgotten, see PHP document today, see the explanation of the difference between include and require, feel this for beginners is a very easy to confuse the place, in this record, so that their own review, but also hope that the PHP friends help.

There are two ways to refer to a file: Require and include. Two ways to provide different use elasticity.

The use of require is as follows require("MyRequireFile.php"); . This function is usually placed at the front of the PHP program, and before the PHP program executes, it is read into the file specified by require to make it a part of the PHP program's Web page. Commonly used functions, you can also use this method to introduce it into the Web page.

include usage methods such as include("MyIncludeFile.php"); . This function is usually placed in the processing part of the process control. The PHP Program page reads the include file before it is read in. This way, you can simplify the process when the program executes.
