# PHP が Web ページのコンテンツを取得するためのいくつかの方法
方法 1: file_get_contents を使用して get でコンテンツを取得するモード。<?php $url='http://www.domain.com/?para=123'; $html= file_get_contents($url); echo$html; ?>
<?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,'',$ctx);
'header'=>"Content-type: application/x-www-form-urlencoded\r\n" . "Content-Length: " . strlen($data) . "\r\n",
'header'=>"Content-type: application/x-www-form-urlencoded\r\n" . "Content-Length: " .strlen($data) . "\r\n". "cookie:cookie1=c1;cookie2=c2\r\n";
<?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: fopen を使用して URL を開き、投稿モードでコンテンツを取得します。<?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$w; ?>
<?php functionget_url ($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) { returnfalse; }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 functionGetUrlHTML($url,$cookie=false) { $rowdata= get_url($url,$cookie); if($rowdata) { $body=stristr($rowdata,"\r\n\r\n"); $body=substr($body,4,strlen($body)); return$body; } returnfalse; } ?>
<?php functionHTTP_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 $data foreach($dataas $key=>$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; } ?>
<?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; ?>
<?php $fh= file_get_contents('http://www.webkaka.com/'); echo $fh; ?>
<?php $fh = fopen('http://www.webkaka.com/', 'r'); if($fh){ while(!feof($fh)) { echo fgets($fh); } } ?>
<?php // 创建一个新cURL资源 $ch = curl_init(); // 设置URL和相应的选项 curl_setopt($ch, CURLOPT_URL, "http://www.webkaka.com/"); curl_setopt($ch, CURLOPT_HEADER, false); // 抓取URL并把它传递给浏览器 data=curlexec(ch); echo $data; //关闭cURL资源,并且释放系统资源 curl_close($ch); ?>
