使用PHP如何从谷歌搜索结果中获得最终url目的地?例如

我想得到

http://www.windowsphone.com/en-us/how-to/wp8/start/whats-new-in-windows-phone

从

http://www.google.com.my/url?sa=t&rct=j&q=&esrc=s&source=web&cd=1&cad=rja&ved=0CC4QFjAA&url=http%3A%2F%2Fwww.windowsphone.com%2Fen-us%2Fhow-to%2Fwp8%2Fstart%2Fwhats-new-in-windows-phone&ei=U0-vUa7HDseOrQenzIGIAg&usg=AFQjCNE7USUy5FcCHAIPreZ7UXBCQ8JUcg&sig2=NwHO-_b51du7XRiknzniXA&bvm=bv.47380653,d.bmk

到目前为止，我已经尝试了以下，但它不工作的谷歌搜索结果链接

<?php
$ch = curl_init("http://www.google.com.my/url?sa=t&etc...");
curl_setopt($ch, CURLOPT_HEADER, true);
curl_setopt($ch, CURLOPT_NOBODY, true);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$response = curl_exec($ch);
curl_close($ch);
$header = "Location: ";
$pos = strpos($response, $header);
$pos += strlen($header);
$redirect_url = substr($response, $pos, strpos($response, "'r'n", $pos)-$pos);
echo $redirect_url;
?>

这个怎么样?代码更少。不需要每一个。

$url = "http://www.google.com.my/url?sa=t&rct=j&q=&esrc=s&source=web&cd=1&cad=rja&ved=0CC4QFjAA&url=http%3A%2F%2Fwww.windowsphone.com%2Fen-us%2Fhow-to%2Fwp8%2Fstart%2Fwhats-new-in-windows-phone&ei=U0-vUa7HDseOrQenzIGIAg&usg=AFQjCNE7USUy5FcCHAIPreZ7UXBCQ8JUcg&sig2=NwHO-_b51du7XRiknzniXA&bvm=bv.47380653,d.bmk";
$query = parse_url($url, PHP_URL_QUERY );
parse_str($query, $link);
echo $link["url"];

看起来你只是试图从另一个地址中提取和解码地址的一部分。

试试这个:

$url = "http://www.google.com.my/url?sa=t&rct=j&q=&esrc=s&source=web&cd=1&cad=rja&ved=0CC4QFjAA&url=http%3A%2F%2Fwww.windowsphone.com%2Fen-us%2Fhow-to%2Fwp8%2Fstart%2Fwhats-new-in-windows-phone&ei=U0-vUa7HDseOrQenzIGIAg&usg=AFQjCNE7USUy5FcCHAIPreZ7UXBCQ8JUcg&sig2=NwHO-_b51du7XRiknzniXA&bvm=bv.47380653,d.bmk"
$parsed = parse_url($url);
$args = explode('&',$parsed['query']);
foreach($args as $arg) {
    list($name,$val) = explode('=',$arg,2);
    if($name !== 'url') continue;
    $url = urldecode($val);
    break;
}
echo $url;
