The use of require is as follows: require ("MyRequireFile. php ");. this function is usually placed at the beginning of the PHP program. before the PHP program is executed, it will first read the file specified by require to make it a part of the PHP program webpage. this method can also be used to introduce common functions into webpages.

Especially when I use notepad to save Web files from ANSI as a UTF-8, it is easy to appear!

2. use EditPlus to save the file as a UTF-8 (without BOM) file.
