What is the difference between die() and exit() in PHP?

Hello everyone! I started learning PHP and came across two functions that seem to do the same thing: die() and exit(). I've seen them used in different scripts and can't understand what the difference between them is. For example, I write a simple database connection check: ```php $connection = mysqli_connect('localhost', 'user', 'pass', 'db'); if (!$connection) { die('Connection error: ' . mysqli_connect_error()); } ``` But I've also seen some people write exit() instead of die(): ```php if (!$connection) { exit('Connection error: ' . mysqli_connect_error()); } ``` They both stop script execution and output a message. This is confusing. Maybe one of them is deprecated? Or is there some subtle difference in behavior that I'm missing? In the documentation
