exit

Output a message and terminate the current script (PHP 4, PHP 5)
void exit ( [string status] )
void exit ( int status )

Terminates execution of the script.

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.

Return Values

No value is returned.

Examples

<?php

//exit program normally
exit;
exit();
exit(
0);

//exit with an error code
exit(1);

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().
