How to get remote file size without downloading file with PHP?
To get remote file size without downloading file with PHP, we can use the curl_getinfo function.
For instance, we write
function retrieve_remote_file_size($url)
{
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HEADER, true);
curl_setopt($ch, CURLOPT_NOBODY, true);
$data = curl_exec($ch);
$size = curl_getinfo($ch, CURLINFO_CONTENT_LENGTH_DOWNLOAD);
curl_close($ch);
return $size;
}
to define the retrieve_remote_file_size function.
In it, we call curl_init with $url to get the $ch object.
Then we call curl_getinfo with $ch and CURLINFO_CONTENT_LENGTH_DOWNLOAD to get the remote file’s size.
And then we call curl_close with $ch to close the connection.
Conclusion
To get remote file size without downloading file with PHP, we can use the curl_getinfo function.
