exit
(PHP 3, PHP 4, PHP 5)
exit — Output a message and terminate the current scriptDescriptionvoid exit ( [string status] )void exit ( int status )
Terminates execution of the script.
status
If status is a string, this function prints the
status, if set as a string just before exiting.
If status is an integer, that
value will also be used as the exit status. Exit statuses should be in
the range 0 to 254, the exit status 255 is reserved by PHP and shall
not be used. The status 0 is used to terminate the program
successfully.
Note:
PHP >= 4.2.0 does NOT print the status
if it is an integer.
Return Values
No value is returned.
Example 1. exit() example
$filename = '/path/to/data-file'; $file = fopen($filename, 'r') or exit("unable to open file ($filename)");
Example 2. exit() status example
//exit program normally exit; exit(); exit(0); //exit with an error code exit(1); exit(0376); //octal
Notes
Note: Because this is a
language construct and not a function, it cannot be called using
variable functions
Note:
This language construct is equivalent to die().
