- 方法1: 用file_get_contents 以get方式获取内容
- <?php
- $url='http://www.domain.com/?para=123';
- $html = file_get_contents($url);
- echo $html;
- ?>
- 方法2:用file_get_contents函数,以post方式获取url
- <?php
- $url = 'http://www.domain.com/test.php?id=123';
- $data = array ('foo' => 'bar');
- $data = http_build_query($data);
- $opts = array (
- 'http' => array (
- 'method' => 'POST',
- 'header'=> "Content-type: application/x-www-form-urlencoded\\r\\n" .
- "Content-Length: " . strlen($data) . "\\r\\n",
- 'content' => $data
- )
- );
- $ctx = stream_context_create($opts);
- $html = @file_get_contents($url,'',$ctx);
- 如果需要再传递cookie数据,则把
- 'header'=> "Content-type: application/x-www-form-urlencoded\\r\\n" .
- "Content-Length: " . strlen($data) . "\\r\\n",
- 修改为
- 'header'=> "Content-type: application/x-www-form-urlencoded\\r\\n" .
- "Content-Length: " . strlen($data) . "\\r\\n".
- "cookie:cookie1=c1;cookie2=c2\\r\\n" ;
- 即可
- 方法3: 用fopen打开url, 以get方式获取内容
- <?php
- $fp = fopen($url, 'r');
- $header = stream_get_meta_data($fp);//获取报头信息
- while(!feof($fp)) {
- $result .= fgets($fp, 1024);
- }
- echo "url header: {$header} <br>":
- echo "url body: $result";
- fclose($fp);
- ?>
- 方法4: 用fopen打开url, 以post方式获取内容
- <?php
- $data = array ('foo2' => 'bar2','foo3'=>'bar3');
- $data = http_build_query($data);
- $opts = array (
- 'http' => array (
- 'method' => 'POST',
- 'header'=> "Content-type: application/x-www-form-urlencoded\\r\\nCookie:cook1=c3;cook2=c4\\r\\n" .
- "Content-Length: " . strlen($data) . "\\r\\n",
- 'content' => $data
- )
- );
- $context = stream_context_create($opts);
- $html = fopen('http://www.test.com/zzzz.php?id=i3&id2=i4','rb' ,false, $context);
- $w=fread($html,1024);
- echo $w;
- ?>
- 方法5:用fsockopen函数打开url,以get方式获取完整的数据,包括header和body
- <?php
- function get_url ($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/1.1\\r\\n";
- $request .= "Host: $url[host]\\r\\n";
- $request .= "Connection: Close\\r\\n";
- if($cookie) $request.="Cookie: $cookie\\n";
- $request.="\\r\\n";
- fwrite($fp,$request);
- while(!@feof($fp)) {
- $result .= @fgets($fp, 1024);
- }
- fclose($fp);
- return $result;
- }
- }
- //获取url的html部分,去掉header
- function GetUrlHTML($url,$cookie=false)
- {
- $rowdata = get_url($url,$cookie);
- if($rowdata)
- {
- $body= stristr($rowdata,"\\r\\n\\r\\n");
- $body=substr($body,4,strlen($body));
- return $body;
- }
- return false;
- }
- ?>
- 方法6:用fsockopen函数打开url,以POST方式获取完整的数据,包括header和body
- <?php
- function HTTP_Post($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/1.1\\n";
- $request.="Host: ".$URL_Info["host"]."\\n";
- $request.="Referer: $referer\\n";
- $request.="Content-type: application/x-www-form-urlencoded\\n";
- $request.="Content-length: ".strlen($data_string)."\\n";
- $request.="Connection: close\\n";
- $request.="Cookie: $cookie\\n";
- $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7: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
- <?php
- $ch = curl_init();
- $timeout = 5;
- curl_setopt ($ch, CURLOPT_URL, 'http://www.domain.com/');
- curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
- curl_setopt ($ch, CURLOPT_CONNECTTIMEOUT, $timeout);
- $file_contents = curl_exec($ch);
- curl_close($ch);
- echo $file_contents;
- ?>
