In this article, we’ll look at how to get remote file size without downloading file with PHP.
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.
