PHP's Require () performance is similar to include ().
Different, for include (), the file is read and evaluated at the time of Include ();
For Require (), the file is only handled (actually, the file content replaces the request () statement).
This means that if there is code that contains one of these instructions and the code that may perform multiple times, use the request () efficiency is relatively high.
On the other hand, if you read different files each time you perform code, or use include (), because you can set a variable to the file name you want to include, when the parameter is This variable is used when include ().
