There is no difference. Simple :)

the only notable difference is this pun:

Also note that it is your responsibility to die() if necessary.

This is actually a question in w3schools.org's PHP quiz.

I remember missing that question and that's why I always remember this.

die function kill the rest all the page and exit will just jump to next line or next function...that s differnce between in both

[Dormilich]

I doubt that. from the Manual:

[exit] Terminates execution of the script. Shutdown functions and object destructors will always be executed even if exit is called.

Hi,
There is no difference in functionality. They can be used alternatively with following conditions.

die > is used to throw an exception (catchable using eval).
exit > is used to exit the process.

die > will set the error code based on $! or $? if the exception is uncaught.
exit > will set the error code based on its argument.

In short,

die > outputs a message
exit > does not outputs message

Hope this shall help you to understand the difference.

die > is used to throw an exception (catchable using eval).

wrong. neither does die throw an Exception, nor does eval catches one.

let’s get some more precise and quote the Manual:

die:

Description

This language construct is equivalent to exit().

exit:

Description
void exit ([ string $status ] )
void exit ( int $status )

Terminates execution of the script. Shutdown functions and object destructors will always be executed even if exit is called.

exit is a language construct and it can be called without parentheses if no status is passed.

echo also outputs a message #solutionwand
