Apache2，PHP文件始终运行并可从任何请求访问

Question

Is there any way to make a php file always running and accessible from others php files/requests?

I want to make a functions, objects, variables or some others things always running on the server.

Example:

[alwaysrunning.php]

$conn = fsockopen($serverip, $serverport, $errno, $errstr, $ex);

[index.php]

fwrite($conn, $command."
");

Sorry my english and thank you!
