exit
Output a message and terminate the current script
(PHP 4, PHP 5)
void exit ( [string status] )void exit ( int status )
Parameters
- status
If status is a string, this function prints the status 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.
Examples
Example 1355. exit() example
<?php
$filename = '/path/to/data-file';
$file = fopen($filename, 'r')
or exit("unable to open file ($filename)");
?>
Example 1356. exit() status example
<?php
//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().
