EXIT(3) 								 1								   EXIT(3)

exit - Output a message and terminate the current script

void exit ([string $status]) DESCRIPTION
void exit (int $status) Terminates execution of the script. Shutdown functions and object destructors will always be executed even if exit is called. exit is a language construct and it can be called without parentheses if no $status is passed. PARAMETERS
o $status - If $status is a string, this function prints the $status just before exiting. If $status is an integer, that value will be used as the exit status and not printed. 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. EXAMPLES
Example #1 exit example <?php $filename = '/path/to/data-file'; $file = fopen($filename, 'r') or exit("unable to open file ($filename)"); ?> Example #2 exit status example <?php //exit program normally exit; exit(); exit(0); //exit with an error code exit(1); exit(0376); //octal ?> Example #3 Shutdown functions and destructors run regardless <?php class Foo { public function __destruct() { echo 'Destruct: ' . __METHOD__ . '()' . PHP_EOL; } } function shutdown() { echo 'Shutdown: ' . __FUNCTION__ . '()' . PHP_EOL; } $foo = new Foo(); register_shutdown_function('shutdown'); exit(); echo 'This will not be output.'; ?> The above example will output: Shutdown: shutdown() Destruct: Foo::__destruct() 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(3). SEE ALSO
