PHP: Pass through file including mime-type

I would like to use fpassthru to relay files from another server.

The files are stored as static files on a webserver (thus the MIME-type is set correctly by Apache), but when I fpassthru then via PHP, they lose their MIME-type.

Basically what I would like to do is to relay the file as if it came from a static server (i.e. with the same headers or at least with the same MIME-type), but I only want to use one connection to receive both data and MIME-type for performance reasons.

How can I get the MIME-type of the file that I receive with fpassthru (or file_get_contents or another function)?

Get the MIME type with mime_content_type function, then set the Content-Type header using the header function, e.g.:

<?php
$path = '/path/to/local/file.png';
$mime_type = mime_content_type($path) ?: 'application/octet-stream';
$file_size = filesize($path);

header("Content-Type: $mime_type");
header("Content-Length: $file_size");
$fh = fopen($path, 'rb');
fpassthru($fh);
fclose($fh);
