Share a powerful collection class and also simulate PHP multi-process

When doing the collection, you can use file_get_contents () to get the Web source code, but use file_get_contents acquisition, slow, and time-out, bad control. If the collected page does not exist, it will take a long time to wait. Generally, curl is the fastest, followed by the socket, and finally the file_get_contents. now to share with you a very powerful collection class, will be based on your server's current configuration, automatically choose the fastest way. has already encapsulated curl and socket,file_get_contents. The usage is simple: 1, request with Get method Http::d oget (URL);//supermarket time can be ignored, default is 5 seconds Http::d oget (URL, time-out); such as Echo Http::d oget (' http://www.baidu.com '); 2, using the Post method request Http::d opost (URL, data, time-out); Such as $url = ' http://www.canphp.com/test.php '; $data [' name ']= ' riding alone '; $data [' Email ']= ' [email protected] '; Http::d opost ($url, $data, 10); test.php page Receive data $_post[' name ']; $_post[' email ']; this HTTP class can be used not only for collection, but also for a powerful role in simulating PHP asynchronous multi-process. Like index.php and a.php, b.php, c.php. In the index.php Http::d oget (' http://www.canphp.com/a.php ', 1); Http::d oget (' http://www.canphp.com/b.php ', 1); Http::d oget (' http://www.canphp.com/c.php ', 1); a.php, b.php, c.php program respectively in the head PlusIgnore_user_abort (true); Then you can achieve a multi-process. Principle: Send a request via curl or socket to a.php, b.php, c.php, because the timeout time is relatively short, just triggered a.php, b.php, c.php three pages, do not need to wait for data return, connection is interrupted, but a.php, b.php, c.php program Added aIgnore_user_abort (true);Ignores the client connection and continues execution.
