php - What is the difference between echo('exit'); die; and die('exit');? -

-

i have seen code this:

if(something){     echo 'exit program';     die; } ...more code

and others use die:

if(something)   die('exit program'); ...more code

is there inherent difference in when end program, should aware of code comes after it? etcetera

update

i asking mainly, if coding style, or if there real reason why coded 1 way versus another. not asking difference between exit , die is.

no, there no difference; both write "exit" stdout , terminate program.

i prefer die("exit") method it's less typing, easier comment out , semantically clearer.

as far "speed", why care faster? need program die quickly?

re: update

... inherent difference in when end program ...

there no difference, inherent or otherwise. they're identical. second option, die('exit'), single statement, , requires no braces when used if statement; has nothing die , blocks , flow control in c-style languages.

re: comment/second update

which way die matter of personal preference. said, they identical. choose 2nd option reasons listed above: shorter, clearer, cleaner, amounts "better" in opinion.

the difference between exit , die exit allows return non-zero status, while die returns 0. neither function "better", serve different purposes.

so i've got simple form in canvas / iframe facebook app, , i'm trying pass along values post. reading on s.o. , fb's latest docs, understand it, data send via post form can accessed on receiving end $_request object. i read on thread on s.o. in order post forms work need pass along input named "signed_request" value current signed_request (i have signed request working ok otherwise...all login , authentication stuff working fine). isnt mentioned anywhere in official fb docs. so problem comes in $_request object signed request, , bunch of other session stuff. form inputs found. the way can read them set method of form "request" isn't real form method. takes of inputs , sends them args in url. horrible. here's sample page canvas app form i'm using try debug (leaving out authentication stuff): <form enctype="application/x-www-form-urlencoded" method="post" target="_top" id="my_form" action=...
