Question: 1 / 400

What does the die() function do in PHP?

Stops script execution and outputs a message

The die() function in PHP is used to terminate the execution of the script immediately. When invoked, it can also optionally output a message to provide feedback about why the script has ceased operation. This is particularly useful for debugging purposes or when you want to signal that an error has occurred. By incorporating a message, developers can more effectively communicate the reason behind the script termination to anyone who might encounter it.

When evaluating the other options, it's essential to note that the die() function does not return error messages or exit loops, nor does it rerun previously executed commands. Its primary role is to abruptly halt any further processing in the script. This decisive behavior makes it a primary tool for managing flow control during error handling or exceptional circumstances.
