目前我使用下面的函數檢查URL存在,或不使用PHP捲曲
function urlExist($url)
{
$handle = curl_init($url);
if (false === $handle)
{
return false;
}
curl_setopt($handle, CURLOPT_HEADER, false);
curl_setopt($handle, CURLOPT_FAILONERROR, true); // this works
curl_setopt($handle, CURLOPT_HTTPHEADER, Array("User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.15) Gecko/20080623 Firefox/2.0.0.15")); // request as if Firefox
curl_setopt($handle, CURLOPT_NOBODY, true);
curl_setopt($handle, CURLOPT_RETURNTRANSFER, false);
$connectable = curl_exec($handle);
##print $connectable;
curl_close($handle);
return $connectable;
}
它工作正常進行簡單的URL,但對於URL重定向到另一個域
