Explaining the Difference between include() and require() in PHP

Include() and require() are both PHP functions used to include and evaluate the specified file during the script execution. The main difference between include() and require() is how they handle errors:

include(): If the file specified in the include() function is not found or cannot be included, a warning message is generated, but the script will continue to execute.

require(): If the file specified in the require() function is not found or cannot be included, a fatal error is generated, and the script execution is stopped immediately.

Therefore, when using include(), the script will continue running even if the included file is missing, while require() will halt the script execution if the required file is not found.
