php获取页面内容-PHP源码
php 获取页面内容方法1: 用file_get_contents 以get方式获取内容 方法2:用file_get_contents函数,以post方式获取url 'bar'); $data = http_build_query($data); $opts = array ( 'http' => array ( 'method' => 'POST', 'header'=> "Content-type: application/x-www-form-urlencoded\r\n" . "Content-Length: " . strlen($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 ": echo "url body: $result"; fclose($fp); ?> 方法4: 用fopen打开url, 以post方式获取内容 '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 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 $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
