PHP Asynchronous request (can do pseudo-threading)

$fp = Fsockopen ("www.baidu.com", $errno, $errstr, 30);
Stream_set_blocking ($fp, 0); Set as non-blocking request
if (! $fp) die (' Error fsockopen ');
$http = "get/yibu/yibu.php/http/1.1\r\n";
$http. = "host:www.baidu.com\r\n";
$http. = "connection:close\r\n\r\n";
Fwrite ($fp, $http);
Fclose ($FP);

This use Fsockopen to do PHP asynchronous operation, there are shortcomings, may be due to the need to establish a connection and shut down the connection time, and this time depends on the requested server and the requested server network condition, is fsockopen can not solve the problem, which is also a disadvantage, The requested PHP file is actually executed asynchronously.
