php获取远程文件大小

来源：百度知道编辑：UC知道时间：2024/05/22 00:04:25

下面这段php代码是计算远程文件的函数，文件在几MB时能正确运行，到几十MB时就溢出（显示为0MB）了，高手帮忙解决下。
没有PHP专区，只好贴到这来了，不要给我其它语言的代码，只要PHP的。
function remote_filesize($uri,$user='',$pw='')
{
// start output buffering
ob_start();
// initialize curl with given uri
$ch = curl_init($uri);
// make sure we get the header
curl_setopt($ch, CURLOPT_HEADER, 1);
// make it a http HEAD request
curl_setopt($ch, CURLOPT_NOBODY, 1);
// if auth is needed, do it here
if (!empty($user) && !empty($pw))
{
$headers = array('Authorization: Basic ' . base64_encode($user.':'.$pw));
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
}
$okay = curl_exec($ch);
curl_close($ch);
// get the output buffer
$head = ob_get_contents();
// clean the output buffer and return to previous
// buffer settings
ob_end_clean();

// gets you the numeric value from the Content-Length
// fi

你的代码没有问题!
