How PHP uses the socket to send HTTP requests _php tips

This example describes how PHP uses the socket to send HTTP requests. Share to everyone for your reference, specific as follows:

Socket Mode :

$socket = Socket_create (Af_inet, Sock_stream, sol_tcp);
Socket_set_option ($socket, Sol_socket, So_sndtimeo, Array ("SEC" =>20, "USEC" =>0));
Socket_connect ($socket, ' www.baidu.com ',);
It's a newline. Note that the copied code may be followed by a space
$http = <<<eof
get/http/1.0
Accept: */*
user-agent: Lowell-agent
Host:www.baidu.com
connection:close
EOF;
Socket_write ($socket, $http, strlen ($http));
while ($str = Socket_read ($socket, 1024))
{
  echo $str;
}
Socket_close ($socket);

Fsockopen Way :

$fp = Fsockopen ("www.baidu.com", $errno, $errstr,);
if (! $fp) {
  echo $errstr ($errno) <br/>\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);

Original Socket Method :

$fp = Stream_socket_client ("tcp://www.baidu.com:80", $errno, $errstr);
if (! $fp) {
  echo $errstr ($errno) <br/>\n ";
} else {
  $http = <<<eof
get/http/1.0
   accept: */*
user-agent:lowell-agent
Host:www.baidu.com
connection:close
EOF;
  Fwrite ($fp, $http);
  while (!feof ($fp)) {
    echo fgets ($FP, 1024);
  }
  Fclose ($FP);

Stream mode (GET):
