PHP » Control Structures » die()
- Syntax:
- void die([mixed status])
- status
- Message to print or status to return.
Stops the execution of a script.
die() immediately stops the execution of the script. It is often used together with the OR operator, to quit executing when a crucial call fails. The optional status parameter can either be a string or an integer. Strings are printed and integers are returned as the exit status.
Examples
Code:
<?php
@mysql_connect("host_that_does_not_exist")
or die("Could not connect to db. Die.");
?> Output:
Could not connect to db. Die.Explanation:
If something like a connection to a database cannot be made, if is often not meaningful to continue executing the script.
