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
