php獲取body
Ⅰ php獲取指定網頁內容
一、用file_get_contents函數,以post方式獲取url
<?php
$url='http://www.domain.com/test.php?id=123';
$data=array('foo'=>'bar');
$data= http_build_query($data);
$opts=array(
'http'=>array(
'method'=>'POST',
'header'=>"Content-type: application/x-www-form-urlencoded " .
"Content-Length: " .strlen($data) ." ",
'content'=>$data
)
);
$ctx= stream_context_create($opts);
$html= @file_get_contents($url,'',$ctx);
二、用file_get_contents以get方式獲取內容
<?php
$url='http://www.domain.com/?para=123';
$html=file_get_contents($url);
echo$html;
?>
三、用fopen打開url, 以get方式獲取內容
<?php
$fp=fopen($url,'r');
$header= stream_get_meta_data($fp);//獲取報頭信息
while(!feof($fp)) {
$result.=fgets($fp, 1024);
}
echo"url header: {$header} <br>":
echo"url body: $result";
fclose($fp);
?>
四、用fopen打開url, 以post方式獲取內容
<?php
$data=array('foo2'=>'bar2','foo3'=>'bar3');
$data= http_build_query($data);
$opts=array(
'http'=>array(
'method'=>'POST',
'header'=>"Content-type: application/x-www-form-
urlencoded Cookie:cook1=c3;cook2=c4 " .
"Content-Length: " .strlen($data) ." ",
'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;
?>
五、使用curl庫，使用curl庫之前，可能需要查看一下php.ini是否已經打開了curl擴展
<?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;
?>
Ⅱ 怎麼用php讀取並顯示另一個php文件的內容
示例代碼1: 用file_get_contents 以get方式獲取內容
代碼如下:
<?php
$url='';
$html=file_get_contents($url);
//print_r($http_response_header);
ec($html);
printhr();
printarr($http_response_header);
printhr();
?>
示例代碼2: 用fopen打開url, 以get方式獲取內容
代碼如下:
<?
$fp=fopen($url,'r');
printarr(stream_get_meta_data($fp));
printhr();
while(!feof($fp)){
$result.=fgets($fp,1024);
}
echo"url body:$result";
printhr();
fclose($fp);
?>
示例代碼3：用file_get_contents函數,以post方式獲取url
代碼如下:
<?php
$data=array('foo'=>'bar');
$data=http_build_query($data);
$opts=array(
'http'=>array(
'method'=>'POST',
'header'=>"Content-type: application/x-www-form-urlencodedrn".
"Content-Length: ".strlen($data)."rn",
'content'=>$data
),
);
$context=stream_context_create($opts);
$html=file_get_contents('',false,$context);
echo$html;
?>
示例代碼4：用fsockopen函數打開url，以get方式獲取完整的數據，包括header和body
代碼如下:
<?
functionget_url($url,$cookie=false){
$url=parse_url($url);
$query=$url[path]."?".$url[query];
ec("Query:".$query);
$fp=fsockopen($url[host],$url[port]?$url[port]:80,$errno,$errstr,30);
if(!$fp){
returnfalse;
}else{
$request="GET$queryHTTP/1.1rn";
$request.="Host:$url[host]rn";
$request.="Connection: Closern";
if($cookie)$request.="Cookie:$cookien";
$request.="rn";
fwrite($fp,$request);
while(!@feof($fp)){
$result.=@fgets($fp,1024);
}
fclose($fp);
return$result;
}
}
//獲取url的html部分，去掉header
functionGetUrlHTML($url,$cookie=false){
$rowdata=get_url($url,$cookie);
if($rowdata)
{
$body=stristr($rowdata,"rnrn");
$body=substr($body,4,strlen($body));
return$body;
}
returnfalse;
}
?>
示例代碼5：用fsockopen函數打開url，以POST方式獲取完整的數據，包括header和body
代碼如下:
<?
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/1.1n";
$request.="Host: ".$URL_Info["host"]."n";
$request.="Referer:$referern";
$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;
}
printhr();
?>
示例代碼6:使用curl庫，使用curl庫之前，你可能需要查看一下php.ini，查看是否已經打開了curl擴展
代碼如下:
<?
$ch = curl_init();
$timeout = 5;
curl_setopt ($ch, CURLOPT_URL, '');
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt ($ch, CURLOPT_CONNECTTIMEOUT, $timeout);
$file_contents = curl_exec($ch);
curl_close($ch);
echo $file_contents;
?>
關於curl庫：
curl官方網站
curl 是使用URL語法的傳送文件工具，支持FTP、FTPS、HTTP HTPPS SCP SFTP TFTP TELNET DICT FILE和LDAP。curl 支持SSL證書、HTTP POST、HTTP PUT 、FTP 上傳，kerberos、基於HTT格式的上傳、代理、cookie、用戶＋口令證明、文件傳送恢復、http代理通道和大量其他有用的技巧
復制代碼 代碼如下:
<?
functionprintarr(array$arr)
{
echo"<br> Row field count: ".count($arr)."<br>";
foreach($arras$key=>$value)
{
echo"$key=$value <br>";
}
}
?>
Ⅲ 如何在php中獲取curl請求的請求頭信息及相應頭信息
<?php
$url='http://demo.zjmainstay.cn';
$ch=curl_init($url);
curl_setopt($ch,CURLOPT_HEADER,true);//返回頭信息
curl_setopt($ch,CURLOPT_NOBODY,true);//不返回內容
curl_setopt($ch,CURLOPT_RETURNTRANSFER,1);//返回數據不直接輸出
$content=curl_exec($ch);//執行並存儲結果
curl_close($ch);
echo$content;
