PHP功能強大的CURL POST類

本文主要為大家詳細介紹了功能強大的PHP POST提交資料類，代碼簡潔且具有一定的參考價值，感興趣的小夥伴們可以參考一下。希望對大家有所協助。

具體內容如下

<?php 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;  }}?>
