方法一：

/**
 * 发送post请求
 * @param string $url 请求地址
 * @param array $post_data post键值对数据
 * @return string
 */
function send_post($url, $post_data) {
 
  $postdata = http_build_query($post_data);
  $options = array(
    'http' => array(
      'method' => 'POST',
      'header' => 'Content-type:application/x-www-form-urlencoded',
      'content' => $postdata,
      'timeout' => 15 * 60 // 超时时间（单位:s）
    )
  );
  $context = stream_context_create($options);
  $result = file_get_contents($url, false, $context);
 
  return $result;
}
 
//使用方法
$post_data = array(
  'username' => 'stclair2201',
  'password' => 'handan'
);
send_post('http://www.jb51.net', $post_data);

方法二 Socket版本

<?php
/**
 * Socket版本
 * 使用方法：
 * $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,$port = 80,$timeout = 30) {
  $socket = fsockopen($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;
  }
 
  $data = "";
  while (!feof($socket)) {
    $data .= fgets($socket, 4096);
  }
 
  return $data;
}
?>

方法三 curl版本

<?php
/**
 * Curl版本
 * 使用方法：
 * $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;
}
?>

下面是其他网友的方法：

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 $file_contents;
  }
  public static function post2($url, $data){//file_get_content
     
    $postdata = http_build_query(
      $data
    );
     
    $opts = array('http' =>
           array(
             'method' => 'POST',
             'header' => 'Content-type: application/x-www-form-urlencoded',
             'content' => $postdata
           )
    );
     
    $context = stream_context_create($opts);
    $result = file_get_contents($url, false, $context);
    return $result;
  }
  public static function post3($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;
  }
}

对于远程请求，有很多种方法。今天，LZ就搜罗了六种，供大家参考。

1、用file_get_contents 以get方式获取内容：

<?php
$url='http://www.ido321.com/';
$html = file_get_contents($url);
echo $html;
?>

2、用fopen打开url，用get方式获取

$fp = fopen($url, 'r');
stream_get_meta_data($fp);
while(!feof($fp)) {
$result .= fgets($fp, 1024);
}
echo "url body: $result";
fclose($fp);

3、用file_get_contents 以post方式获取内容：

$data = array ('foo' => 'bar');
$data = http_build_query($data);
 
$opts = array (
'http' => array (
'method' => 'POST',
'header'=> "Content-type: application/x-www-form-urlencodedrn" .
'Content-Length: ' . strlen($data) . 'rn',
'content' => $data
)
);
 
$context = stream_context_create($opts);
$html = file_get_contents('http://localhost/e/admin/test.html', false, $context);
 
echo $html;

4、用fsockopen函数打开url，以get方式获取完整的数据，包括header和body,fsockopen需要 PHP.ini 中 allow_url_fopen 选项开启

function get_url ($url,$cookie=false)
{
$url = parse_url($url);
$query = $url[path].'?'.$url[query];
echo 'Query:'.$query;
$fp = fsockopen( $url[host], $url[port]?$url[port]:80 , $errno, $errstr, 30);
if (!$fp) {
return false;
} else {
$request = 'GET $query HTTP/1.1rn';
$request .= 'Host: $url[host]rn';
$request .= 'Connection: Closern';
if($cookie) $request.='Cookie:  $cookien';
$request.='rn';
fwrite($fp,$request);
while(!@feof($fp)) {
$result .= @fgets($fp, 1024);
}
fclose($fp);
return $result;
}
}
//获取url的html部分，去掉header
function GetUrlHTML($url,$cookie=false)
{
$rowdata = get_url($url,$cookie);
if($rowdata)
{
$body= stristr($rowdata,'rnrn');
$body=substr($body,4,strlen($body));
return $body;
}
 
return false;
}

5、用fsockopen函数打开url，以POST方式获取完整的数据，包括header和body

function HTTP_Post($URL,$data,$cookie, $referrer='')
{
 
// parsing the given URL
$URL_Info=parse_url($URL);
 
// Building referrer
if($referrer=='') // if not given use this script as referrer
$referrer='111';
 
// making string from $data
foreach($data as $key=>$value)
$values[]='$key='.urlencode($value);
$data_string=implode('&',$values);
 
// Find out which port is needed – if not given use standard (=80)
if(!isset($URL_Info['port']))
$URL_Info['port']=80;
 
// building POST-request:
$request.="POST ".$URL_Info['path']." HTTP/1.1n";
$request.="Host: ".$URL_Info['host']."n";
$request.="Referer: $referern";
$request.="Content-type: application/x-www-form-urlencodedn";
$request.='Content-length: '.strlen($data_string)."n";
$request.='Connection: closen';
 
$request.='Cookie:  $cookien';
 
$request.='n';
$request.=$data_string.'n';
 
$fp = fsockopen($URL_Info['host'],$URL_Info['port']);
fputs($fp, $request);
while(!feof($fp)) {
$result .= fgets($fp, 1024);
}
fclose($fp);
 
return $result;
}

6、使用curl库，使用curl库之前，可能需要查看一下php.ini是否已经打开了curl扩展

$ch = curl_init();
$timeout = 5;
curl_setopt ($ch, CURLOPT_URL, ‘http://www.ido321.com/');
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt ($ch, CURLOPT_CONNECTTIMEOUT, $timeout);
$file_contents = curl_exec($ch);
curl_close($ch);
 
echo $file_contents;
