PHP `die()` vs. `exit()`: Are They Different?

Comparing exit() and die() in PHP

When faced with the options of using die() or exit() in PHP, one might assume they hold distinct functionalities. However, upon closer examination, it becomes evident that they are essentially interchangeable.

This equivalence is explicitly stated in the PHP Manual:

• The exit() function's documentation notes "Note: This language construct is equivalent to die()."
• Similarly, the die() function's manual states "This language construct is equivalent to exit()."

Therefore, die() and exit() both serve the same purpose: terminating the script's execution and returning control to the calling environment. They do not differ in their effects or behavior.

Hence, the choice between using die() or exit() is purely a matter of personal preference or coding style.
