Câu trả lời When should I use require vs include ?
Here is an answer to the PHP interview question "When should I use require vs include?":
require vs include in PHP
The require and include statements in PHP are used to include external files into a PHP script. The main difference between them is how they handle errors when the file cannot be included.
require
require is used when the script cannot continue execution if the file is not found or included successfully.
If the file cannot be included, require will throw a fatal error (E_COMPILE_ERROR) and stop the script.
Use require for critical files that are absolutely necessary for the script to run, such as configuration files, class definitions, etc.
include
include is used when the script can still continue execution even if the file is not included successfully.
If the file cannot be included, include will throw a warning (E_WARNING) but the script will continue running.
Use include for optional files that provide additional functionality but are not critical to the core logic of the script.
