I am trying to read a PDF file through a browser (IE and Firefox) using PHP. The files are kept on the server but not in the web area for added security. I use the. I found a simple solution for that: instead of read file I just made a link php script to download the file is a good option.

i fixed the issue editing the code like this: header("Content-Length: ". filesize ($ path)); header("Content-type: application/octet-stream");. readfile() will not present any memory issues, even when sending large files, on for those who face problems on names containing spaces (e.g. "test mmoonneeyy.info"). So to restrict the access to PDF file I've created a page callback, where I've written small piece of code to show the PDF output directly in page.

Just turn off output buffering immediately before the call to Readfile.
You can modify this and add fpassthru instead of fread and while, but it sends all data from begin it would be not fruitful if request is bytes from to from mb file.

This was the only way I found to both protect and transfer very large files with PHP gigabytes.
