How can the use of the die() function improve error handling in PHP scripts?

Using the die() function in PHP scripts can improve error handling by allowing you to display a custom error message and terminate the script execution when an error occurs. This can help provide more information to the developer or user about what went wrong, making it easier to debug and fix the issue.

// Example of using die() function for error handling
$file = 'example.txt';

// Check if the file exists
if (!file_exists($file)) {
    die("Error: File does not exist.");
}

// Continue with the script if the file exists
echo "File exists!";
