Why don't you have a look at the wonderful documentation of PHP? It even contains information about die()

Obviously, die() or its equivalent exit() don't return anything to the script itself; to be precise, this code doesn't make much sense:

if (die())) {
    echo 'are we dead yet?';
}

However, depending on what you pass as the (optional) argument of die() or exit(), it does return something to the caller, i.e. the command that caused your script to run. Its practical use is usually limited to the cli SAPI though, when you call the script from a command line using php /path/to/script.php.

Observe:

die('goodbye cruel world');

This code would print goodbye cruel world and then return an exit status code of 0, signalling to the caller that the process terminated normally.

Another example:

die(1);

When you pass an integer value instead of a string, nothing is printed and the exit status code will be 1, signalling to the caller that the process didn't terminate normally.

Lastly, die() without any arguments is the same as die(0).

The exit status of a process can be changed to signal different kinds of errors that may have occurred, e.g. 1 means general error, 2 means invalid username, etc.

  • it returns nothing. But even if it returns something, that something still can't be used for nothing, since the script is quitting.
  • This is not quite accurate. If die() is called with an integer argument, it returns that value. In a web context, this may not mean much. In a CLI PHP script, that return value is meaningful; it's available for use in the shell.
  • Poor guy. He'd have to click again to see what exit() returns. Spoiler: the answer is void
  • The php docs are the place to look such things up. Nothing can be truer than the information there except it is a documentation bug (but if you want to be that sure better check php's bug tracking system and/or run a test code). By the way: Since die() finishes the execution of PHP, it is quite irrelevant, what the return value is (since the program stops at that point).
  • While your answer is not untrue, it's kinda rude IMO... (everyone has to start somewherer - I'm shocked when i see occasional answers like this, with a bunch of upvotes. To be fair, back in '09, the big code of conduct overhaul hadn't taken place yet...
  • Ah, the good old times ... Did you know that asking questions granted as much reputation as giving answers at that time? Soon people realized this was a good way of gaining tons of reputation and started spamming the platform with completely trivial and absurd questions.
