Description:
------------
There is a problem in the sample code of this URL. 

http://www.php.net/manual/en/ref.pcntl.php

Pcntl_signal is not executed because there is "while". 

Please change as follows. 



Reproduce code:
---------------
<?php
declare(ticks=1);

$pid = pcntl_fork();
if ($pid == -1) {
     die("could not fork");
} else if ($pid) {
     exit(); // we are the parent
} else {
     // we are the child
}

// detatch from the controlling terminal
if (!posix_setsid()) {
   die("could not detach from terminal");
}


function sig_handler($signo)
{

     switch ($signo) {
         case SIGTERM:
             // handle shutdown tasks
             exit;
             break;
         case SIGHUP:
             // handle restart tasks
             break;
         default:
             // handle all other signals
     }

}

// setup signal handlers
pcntl_signal(SIGTERM, "sig_handler");
pcntl_signal(SIGHUP, "sig_handler");

// loop forever performing tasks
while (1) {

   // do something interesting here

}
