The die() function prints a message and exits the current script.The die() in PHP is equivalent to exit()

Syntax:

  die(message)

?>

Answer 2

die( ) function is used to display a message and exit the script. It may be used to print alternate message . Instead of showing error it will show the user friendly message.
die( ) function is only used to print string messages .value of variables cannot print with die( ) function

<?php

die("this is Php die example");

//this will print the message
$x="hello test";

die($x)

//this will show blank screen.
?>
