suresh When it comes to including external files in PHP, there are two popular functions used: require() and include(). The main difference between them lies in how they handle errors.
require() is a language construct that includes and evaluates a specified file during the execution of the script. If the file is not found or there is an error in including it, require() will cause a fatal error and halt the script execution.
include(), on the other hand, is also a language construct that includes and evaluates the specified file during the script execution. However, if the file is not found or there is an error, include() will only produce a warning and allow the script to continue running.
In summary, require() is more strict and preferred when the included file is essential for the script to run correctly, while include() is more lenient and can be used when the included file is optional.
