PHP除了做网站，还有一些特殊命令需要探索，我也是刚接触这些，这里把整理的资料分享给大家：
<?php
echo "Here is my little script";
function endScript(){
echo "My little Script has finished";
}
register_shutdown_function(‘endScript‘);
?>
<?php
function endScript(){
echo "My little Script has finished";
}
register_shutdown_function(‘endScript‘);
$result = some_intricate_function()
if($result == 0){
exit();
}
$result = some_other_intricate_function()
if($result == 0){
exit();
}
/* and this keeps reoccurring */
?>
<?php
function shutdown()
{
// This is our shutdown function, in
// here we can do any last operations
// before the script is complete.
echo ‘Script executed with success‘, PHP_EOL;
}
register_shutdown_function(‘shutdown‘);
?>
