why so long winded? simply "die it out" as it follows:



<?php

function die_script($errmsg)

  die ("$errmsg</body></html>");

?>

You may use die() or the equivalent exit() after a redirection ( via the header statement )



<code>

header("location : http://www.differentpage.com");

die();

<code>



this may seem strange but you have to rememeber that header affects the client not the server script ( in fact it will continue to be executed if you dont stop it)

of course you can let the script continue but someone forget this behaviour and get "strange errors"

It's very useful on websites to have all your code in functions, then use "return" instead of die. For example:



function log_in() {

    if(!isset($_POST[password])) {

        print "You must supply a password.";

        return;

    }



// rest of the login function here

}



This way it exits out of the function, gives an error message, but doesn't keep the website from finishing loading.

The die function can also be used within variables and arrays, as long as it is not within quotes.



Example:



$_POST[die];



This will quit the script as it would if you just called die; You can, however, send die as a POST variable as seen below:



$_POST['die'];

If you want to issue die on a file that is inside an include, it will keep everything else from running through and finishing.

You can prevent this by using return;. It ends the current file but lets the others keep going.

Perhaps the Coldfusion query below can be answered as follows:

Using return instead of exit is to prefer when you want the script that you have included inside another script to die but continue to execute the main script.

A useful way of preventing this is to wrap the die function :



<?php

function die_script($errmsg)

{

 print $errmsg . "</body></html>";

 die;

}

?>

die(__LINE__); won't say the line number because die() wants a string. do die(''.__LINE__); or die(__FUNCTION__ . ':' . __LINE);

To get a perl-like die you can/should append this snipped

 . " File: " . __FILE__ . " on line: " . __LINE__

e.g.

die ("Error" . " File: " . __FILE__ . " on line: " . __LINE__);

Note that using the die() function will stop the entire script after that point from being run, so if you issue the die function within a open HTML tag, the HTML tag will remain open, which can seriously effect the browsers output to the user, expecially if its used inside an open <TABLE> tag.
