Check the links above to see how to correctly configure your web server. Note: If you end up downloading empty files, it means you didn't configure your web server to handle X-SENDFILE header.

(For Nginx use X-Accel-Redirect header instead of X-SENDFILE) $filePath) and web server will take care of file serving, which will require less resources than using PHP readfile. Nginx has a similar X-Accel-Redirect header: Īfter configuring web server to handle X-SENDFILE, just replace readfile($filePath) with header('X-SENDFILE: '.

Apache requires mod_xsendfile module: On Ubuntu may be installed by: apt install libapache2-mod-xsendfile.X-SENDFILE is natively supported by Lighttpd:.PHP will require extra CPU / Memory to read and output file contents and when dealing with large files may reach time / memory limits.Ī better way would be to use PHP to authenticate and grant access to a file, and actual file serving should be delegated to a web server using X-SENDFILE method (requires some web server configuration): filesize($filePath)) ĭownloading files this way is not the best idea especially for large files. Header('Content-Disposition: attachment filename=''. Header('Content-type: application/octet-stream') To force download you may use Content-Type: application/octet-stream header, which is supported by most browsers: function downloadFile($filePath) VDownloader is your multi-purpose all-in-one video downloader that works on most online websites. PHP /* Here is the Download.php file to force download stuff */ In href - you have to add download_file.php along with your URL: If you are doing it with your application itself. Now all that's left to do is for that PHP file to read the contents of the CSV file and print them - the filename=example.csv in the header only suggests to the client browser what name to use for the file, it does not actually fetch the data from the file on the server. Read more about this in the Web Authoring FAQ.Įdit You've already switched to a PHP file to deliver the data - which is necessary to set the Content-disposition header (unless there are some arcane Apache settings that can also do this). The alternative is to send a Content-type of application/octet-stream, but that is a hack (you're basically telling the browser 'I'm not telling you what kind of file this is' and depending on the fact that most browsers will then offer a download dialog) and allegedly causes problems with Internet Explorer.

I'm not sure how well this is supported by various browsers. You can suggest to the browser that it should offer to 'save to disk' right away by sending a Content-disposition header: header('Content-disposition: attachment') This cannot be done reliably, since it's up to the browser to decide what to do with an URL it's been asked to retrieve.
