PHP 中用curl去判断图片或页面是否完整

function check_url($url)

{

$ch = curl_init();

curl_setopt($ch, CURLOPT_URL, $url);

curl_setopt($ch, CURLOPT_HEADER, 1);

curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

$data = curl_exec($ch);

$headers = curl_getinfo($ch);

curl_close($ch);

return $headers['http_code'];

}

$myurl = "http://www.XXX/XXX.JPG";

$satus = check_url($myurl);

if($satus == '200')

echo "Its works";

else

echo "broken url";
