HTTP标头的内容长度mod_deflate问题

Question

Hi I have a HTTP Header in a file called download.php that forces a download.

The PHP Code:

$file = 'https://www.website.com/downloads/'.$download->stitle.'.zip';
header('Content-Type: application/octet-stream');
header('Content-Disposition: attachment; filename='.basename($file));
header('Expires: 0');
header('Cache-Control: must-revalidate');
header('Pragma: public');
header('Content-Length: ' . filesize($file));

The download starts without a problem, but is always corrupt and the wrong size?

I am using gzip compression which I assume is causing the content-length to be incorrect for the download as the file is 603kb but the download window is saying 2.2kb.

.htaccess:

# compress text, html, javascript, css, xml:
AddOutputFilterByType DEFLATE text/plain \
text/html \
text/xml \
text/css \
text/x-component \
application/atom+xml \
application/xml \
application/xhtml+xml \
application/rss+xml \
application/javascript \
application/x-javascript \
application/json \
application/vnd.ms-fontobject \
application/x-font-ttf \
application/x-font-woff \
application/font-woff2 \
application/x-web-app-manifest+json \
image/svg+xml \
image/x-icon


# Or, compress certain file types by extension:
<files *.html>
SetOutputFilter DEFLATE
</files> 

I added the following to exclude zip files and the download script:

SetOutputFilter DEFLATE
SetEnvIfNoCase Request_URI \.zip$ no-gzip dont-vary
SetEnvIfNoCase Request_URI download\.php$ no-gzip dont-vary

But the downloaded file is still corrupt and the wrong size (7.7kb). The download window now displays no file size.

What am I doing wrong?

Edit: I am getting the warning: filesize(): stat failed for https://www.website.com/downloads/free-font-family-poppins.zip

If I go to the location the file begins downloading with the correct size, so the file exists, I also changed the permissions of the file and folder to 777 to check it wasn't a permission problem, but still getting the same error.

Found the solution.

filesize() function does not accept HTTP or HTTPS.

Changed the file location to the server filepath and is now functioning correctly.
