Beware that when using PHP on the command line, die("Error") simply prints "Error" to STDOUT and terminates the program with a normal exit code of 0.
If you are looking to follow UNIX conventions for CLI programs, you may consider the following:
<?php
fwrite(STDERR, "An error occurred.\n");
exit(1); // A response code other than 0 is a failure
?>
In this way, when you pipe STDOUT to a file, you may see error messages in the console and BASH scripts can test for a response code of 0 for success:
rc@adl-dev-01:~$ php die.php > test
An error occurred.
rc@adl-dev-01:~$ echo $?
1
Ideally, PHP would write all Warnings, Fatal Errors, etc on STDERR, but that's another story.
Description
This language construct is equivalent to exit().

You can use this function for mysql connection.
For example:
<?php
$conn = mysql_connection("localhost","root",12345678);
if(!$conn){
die("Couldn't connected mysql");
}
?>
So if you can't connect to mysql you will take the message.

If you are using auto append file (auto_append_file ="_end.php";) on your php.ini, be carefull on using die anywhere you want your appended file to be called. Souds obvious now but took me a good 1 hour to realise why one script was not appending end file as expected.
I solved using `return` instead; it works anywhere not just inside functions and the effect is pretty much the same as die.

die doesn't prevent destructors from being run, so the script doesn't exit immediately, it still goes through cleanup routines.

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.

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__);
