PHP three ways to send post requests _php instance

Method One:

/**
 * Send POST request
 * @param string $url request address
 * @param array $post _data post key value pair data
 * @return string
* *  function Send_post ($url, $post _data) {

$postdata = http_build_query ($post _data);
$options = Array ('
http ' => Array (
' method ' => ' POST ',
' header ' => ' Content-type:ap Plication/x-www-form-urlencoded ',
' content ' => $postdata,
' timeout ' => 15 * 60//Timeout (unit: s) 
   )
);
$context = Stream_context_create ($options);
$result = File_get_contents ($url, False, $context);

return $result;
}

Use method
$post _data = array (
' username ' => ' stclair2201 ', ' Password ' => ' Handan '
);
Send_post (' http://www.jb51.net ', $post _data);

Method Two: Socket version

<?php/** * Socket Version * Use method: * $post _string = "App=socket&version=beta";
 * Request_by_socket (' chajia8.com ', '/restserver.php ', $post _string); * * Function Request_by_socket ($remote _server, $remote _path, $post _string, $port =, $timeout =) {   $socket
= Fsockopen ($remote _server, $port, $errno, $errstr, $timeout);
  if (! $socket) Die ("$errstr ($errno)");
  fwrite ($socket, "POST $remote _path http/1.0");
  fwrite ($socket, "User-agent:socket Example");
  fwrite ($socket, "HOST: $remote _server");
  fwrite ($socket, "content-type:application/x-www-form-urlencoded");   fwrite ($socket, "Content-length:". (Strlen ($post _string) + 8).
"");
  fwrite ($socket, "accept:*/*");
  fwrite ($socket, "");
  fwrite ($socket, "mypost= $post _string");
  fwrite ($socket, "");
   $header = "";   while ($str = Trim (fgets ($socket, 4096)) {     $header. = $Str
&NBSP;&NBSP}    $data = "";   while (!feof ($socket)) {     $data. = Fgets ($socket, 4096);   }   
return $data; }?>

Method III: Curl version

<?php
/**
 * Curl Version
 * Use method:
 * $post _string = "App=request&version=beta";
 * Request_by_curl (' http://www.jb51.net/restServer.php ', $post _string);
 * *
function Request_by_curl ($remote _server, $post _string) {
$ch = Curl_init ();
curl_setopt ($ch, Curlopt_url, $remote _server);
curl_setopt ($ch, Curlopt_postfields, ' mypost= '. $post _string);
curl_setopt ($ch, Curlopt_returntransfer, true);
curl_setopt ($ch, Curlopt_useragent, "jb51.net ' s Curl Example beta");
$data = curl_exec ($ch);
Curl_close ($ch);

return $data;

Here are the methods of other netizens:

Class request{public static function post ($url, $post _data = ', $timeout = 5) {//curl $ch = Curl_init ();
    curl_setopt ($ch, Curlopt_url, $url);
    curl_setopt ($ch, Curlopt_post, 1);
    if ($post _data!= ') {curl_setopt ($ch, Curlopt_postfields, $post _data); 
    curl_setopt ($ch, Curlopt_returntransfer, 1);
    curl_setopt ($ch, Curlopt_connecttimeout, $timeout);
    curl_setopt ($ch, Curlopt_header, false);
    $file _contents = curl_exec ($ch);
    Curl_close ($ch);
  return $file _contents; 
    
    The public static function Post2 ($url, $data) {//file_get_content $postdata = http_build_query ($data); $opts = Array (' http ' => Array (' method ' => ' POST ', ' header ' => ' Co
    
    ntent-type:application/x-www-form-urlencoded ', ' content ' => $postdata));
    $context = Stream_context_create ($opts);
    $result = File_get_contents ($url, False, $context);
return $result;  The public static function Post3 ($host, $path, $query, $others = ') {//fsocket $post = ' Post $path http/1.1\r\nhost: $host \
    r\n ";
    $post. = "content-type:application/x-www-form-";
    $post. = "Urlencoded\r\n${others}";
    $post. = "User-agent:mozilla 4.0\r\ncontent-length:"; $post. =strlen ($query). "
    \r\nconnection:close\r\n\r\n$query ";
    $h =fsockopen ($host, 80);
    Fwrite ($h, $post); For ($a =0, $r = ';!
        $a;) {$b =fread ($h, 8192);
        $r. = $b;
      $a = (($b = = ")? 1:0);
    } fclose ($h);
  return $r; }
}
