This article mainly introduces how sockets in PHP send HTTP requests. Interested friends can refer to it. I hope it will be helpful to everyone.
socket method:
$socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP); //socket_set_option($socket, SOL_SOCKET, SO_SNDTIMEO, array("sec"=>20, "usec"=>0)); socket_connect($socket, 'www.baidu.com', 80); //里面的换行代表 \r\n 注意拷贝的代码后面可能有空格 $http = << Copy after login
fsockopen Method:
$fp = fsockopen("www.baidu.com", 80, $errno, $errstr, 30); if (!$fp) { echo "$errstr ($errno)
\n"; } else { $out = "GET / HTTP/1.1\r\n"; $out .= "Host: www.baidu.com\r\n"; $out .= "Connection: Close\r\n\r\n"; fwrite($fp, $http); while (!feof($fp)) { echo fgets($fp, 128); } fclose($fp); }
##stream Method (get):
$http = <<array( 'header' => $http, 'timeout'=>1, //超时 秒 'method' => 'GET', //默认方式 'protocol_version' => '1.1', //默认为 1.0 ), ); $context = stream_context_create($hdrs); echo file_get_contents('http://www.baidu.com', 0, $context);
stream method post:
$postdata = http_build_query(array('act'=>'save', 'id'=>387171)); $http = <<array( 'header' => $http, 'timeout'=>1, //超时 秒 'method' => 'POST', 'content' => $postdata, 'protocol_version' => '1.1', //默认为 1.0 ), ); $context = stream_context_create($hdrs); echo file_get_contents('http://test.cm/song.php', 0, $context);
Note: The Host header must be included in http1.1, but it does not need to be included in http1.0
