方法1: 用file_get_contents 以get方式获取内容
-
-
$url='';
-
$html = file_get_contents($url);
-
echo $html;
-
?>
方法2: 用fopen打开url, 以get方式获取内容
-
stream_get_meta_data($fp);
-
while(!feof($fp)) {
-
$result .= fgets($fp, 1024);
-
}
-
echo "url body: $result";
-
fclose($fp);
-
?>
方法3:用file_get_contents函数,以post方式获取url
-
-
$data = array ('foo' => 'bar');
-
-
$data = http_build_query($data);
-
$opts = array (
-
"white-space:pre"> 'http' => array (
-
"white-space:pre"> 'method' => 'POST',
-
"white-space:pre"> 'header'=> "Content-type: application/x-www-form-urlencoded\r\n" .
-
"white-space:pre"> "Content-Length: " . strlen($data) . "\r\n",
-
"white-space:pre"> 'content' => $data
-
"white-space:pre"> )
-
);
-
-
$context = stream_context_create($opts);
-
$html = file_get_contents('', false, $context);
-
echo $html;
-
?>
方法4:用fsockopen函数打开url,以get方式获取完整的数据,包括header和body,fsockopen需要 PHP.ini 中 allow_url_fopen 选项开启
-
-
function get_url ($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()) {
-
$result .= @fgets($fp, 1024);
-
}
-
fclose($fp);
-
return $result;
-
}
-
}
-
-
function GetUrlHTML($url,$cookie=false)
-
{
-
$rowdata = get_url($url,$cookie);
-
if($rowdata)
-
{
-
$body= stristr($rowdata,"\r\n\r\n");
-
$body=substr($body,4,strlen($body));
-
return $body;
-
}
-
return false;
-
}
-
?>
方法5:用fsockopen函数打开url,以POST方式获取完整的数据,包括header和body
-
-
function HTTP_Post($URL,$data,$cookie, $referrer="")
-
{
-
-
$URL_Info=parse_url($URL);
-
-
if($referrer=="")
-
$referrer="111";
-
-
foreach($data as $key=>$value)
-
$values[]="$key=".urlencode($value);
-
$data_string=implode("&",$values);
-
-
if(!isset($URL_Info["port"]))
-
$URL_Info["port"]=80;
-
-
$request.="POST ".$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6: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
-
-
$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;
-
?>
