本文实例讲述了php实现模拟post请求的方法。分享给大家供大家参考。具体如下：

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=array()){//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;
 }
}
$url='http://******/con/Inter.php';
$data=Request::post($url,array('api'=>'tag_list'));
$data2=Request::post2($url,array('api'=>'tag_list'));
echo $data;
