php调用远路url的六种方法

ta($fp));

printhr();
?? while(!feof($fp)) {
?????? $result .= fgets($fp, 1024);
}
echo "url body:??? $result";
?? printhr();

?? fclose($fp);
?? ?>

示例代码3：用file_get_contents函数,以post方式获取url

?? ?? $data = array ('foo' => 'bar');
?? $data = http_build_query($data);

?? $opts = array (
'http' => array (
?? 'method' => 'POST',
??? 'header'=> "Content-type: application/x-www-form-urlencoded\r\n" .
???? "Content-Length: " . strlen($data) . "\r\n",
?? 'content' => $data
?? ),
?? );

$context = stream_context_create($opts);
$html = file_get_contents('http://localhost/e/admin/test.html', false, $context);

echo $html;
?>

示例代码4：用fsockopen函数打开url，以get方式获取完整的数据，包括header和body

function get_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) {
?????? 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,$request);
?????? while(!@feof($fp)) {
???????? $result .= @fgets($fp, 1024);
?????? }
?????? fclose($fp);
?????? return $result;
}
}


//获取url的html部分，去掉header
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;

}


?>

示例代码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="") {

// 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 $data
foreach($data as $key=>$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;
}
printhr();
?>
示例代码6:使用curl库，使用curl库之前，你可能需要查看一下php.ini，查看是否已经打开了curl扩展


$ch = curl_init();
$timeout = 5;
curl_setopt ($ch, CURLOPT_URL, 'http://www.baidu.com/');
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt ($ch, CURLOPT_CONNECTTIMEOUT, $timeout);
$file_contents = curl_exec($ch);
curl_close($ch);

echo $file_contents;
?>
关于curl库：
curl官方网站http://curl.haxx.se/
curl 是使用URL语法的传送文件工具，支持FTP、FTPS、HTTP HTPPS SCP SFTP TFTP TELNET DICT FILE和LDAP。curl 支持SSL证书、HTTP POST、HTTP PUT 、FTP 上传，kerberos、基于HTT格式的上传、代理、cookie、用户＋口令证明、文件传送恢复、http代理通道和大量其他有用的技巧


function printarr(array $arr)
{
??? echo "
Row field count: ".count($arr)."
";
??? foreach($arr as $key=>$value)
??? {
????? ?
??????????? echo "$key=$value???
";
??? }
}
?>
