[PHP][Curl] 取得302轉址後的url

PHP 利用 curl 取得轉址後的 url

function curl_302($url) {
    $ch = curl_init();
    curl_setopt($ch , CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch , CURLOPT_URL, $url);
    curl_setopt($ch , CURLOPT_FOLLOWLOCATION, 1); // 302 redirect
    $data  = curl_exec($ch); // return page content
    $info  = curl_getinfo($ch);
    $error = curl_errno($ch);
    curl_close($ch);
    
    if (!$error) 
    {
     return  $info["url"];
    } else {
     return FALSE;
    }
}

PS.一定要先執行curl_exec() 才可執行 curl_getinfo() 或 curl_errno()
