PHP 获取重定向之后的地址

函数说明

可以直接获取网址重定向 (302，301) 之后的地址

函数源码

function get_location($url,$ua=0){

$ch = curl_init();

curl_setopt($ch, CURLOPT_URL, $url);

curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);

curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);

$httpheader[] = "Accept:*/*";

$httpheader[] = "Accept-Encoding:gzip,deflate,sdch";

$httpheader[] = "Accept-Language:zh-CN,zh;q=0.8";

$httpheader[] = "Connection:close";

curl_setopt($ch, CURLOPT_HTTPHEADER, $httpheader);

curl_setopt($ch, CURLOPT_HEADER, true);

if ($ua) {

curl_setopt($ch, CURLOPT_USERAGENT, $ua);

} else {

curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/5.0 (Linux; U; Android 4.0.4; es-mx; HTC_One_X Build/IMM76D) AppleWebKit/534.30 (KHTML, like Gecko) Version/4.0");

}

curl_setopt($ch, CURLOPT_NOBODY, 1);

curl_setopt($ch, CURLOPT_ENCODING, "gzip");

curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);

curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

$ret = curl_exec($ch);

curl_close($ch);

preg_match("/Location: (.*?)\r\n/iU",$ret,$location);

return $location[1];

}

使用示例

//使用默认ua

echo get_location('http://example.com');

//使用自定义ua

$ua = 'Mozilla/5.0 (iPhone; CPU iPhone OS 13_3 like Mac OS X) AppleWebKit/604.3.5 (KHTML, like Gecko) Version/13.0 MQQBrowser/9.0.0 Mobile/15B87 Safari/604.1 MttCustomUA/2 QBWebViewType/1 WKType/1';

echo get_location('http://example.com'，$ua);
