➤ The exit() function in PHP is an inbuilt function which is used to output a message and terminate the current script. • The exit() function returns nothing. • The exit() function only terminates the execution of the script. For instance:

$x = 10;
$y = 5;
exit; // Terminates the execution of the script
echo $x + $y; // This line will not be executed

$x = 10;
$y = 5;
exit("terminate the current script"); // Output a message
echo $x + $y; // This line will not be executed
