PHP发送HTTP请求的6种方法,知道4种算你牛

方法1: 用 file_get_contents 以get方式获取内容：

方法2: 用fopen打开url, 以get方式获取内容：

fgets ($fp, 1024);}echo $body;fclose($fp);?>

方法3：用 file_get_contents 函数,以post方式获取url

‘bar’);$data = http_build_query($data);$opts = array (‘http’ => array (‘method’ => ‘POST’,’header’=> ‘Content-type: application/x-www-form-urlencodedrn’ .’Content-Length: ‘ . strlen ($data) . ‘\r\n’,’content’ => $data));$context = stream_context_create($opts);$ html = file_get_contents(‘ false, $context);echo $html;?>

方法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

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

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

$value)$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/1.1\n”;$request.=”Host: “.$URL_Info[“host”].”\n”;$request.=”Referer: $referer\n”;$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;}?>

方法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

2. $ ch = curl_init();

3. $timeout =5;

4. curl_setopt ($ch, CURLOPT_URL,'

5. curl_setopt ($ch, CURLOPT_RETURNTRANSFER,1);

6. curl_setopt ($ch, CURLOPT_CONNECTTIMEOUT, $timeout);

7. $file_contents = curl_exec($ch);

8. curl_close($ch);

10. echo $file_contents;

11. ?>
