It does not mean that you can fully escape memory exhaustion, though: if you are reading too much at a time, you can still encounter it. That is why in my library I use a helper function "speedLimit" to calculate whether selected speed limit will fit the available memory while allowing some headroom. You can read comments in the code itself for more details and raise issues for the library, if you think something is incorrect there especially since it's WIP at the moment of writing this , but so far I am able to get consistent behavior with it.

To anyone that's had problems with Readfile reading large files into memory the problem is not Readfile itself, it's because you have output buffering on. Just turn off output buffering immediately before the call to Readfile. Most if not all browsers will simply download files with that type. If you use proper MIME types and inline Content-Disposition , browsers will have better default actions for some of them. in case of images, browsers will display them, which is probably what you'd want. To deliver the file with the proper MIME type, the easiest way is to use: header 'Content-Type: '.

If you are using the procedures outlined in this article to force sending a file to a user, you may find that the "Content-Length" header is not being sent on some servers. The reason this occurs is because some servers are setup by default to enable gzip compression, which sends an additional header for such operations. This additional header is "Transfer-Encoding: chunked" which essentially overrides the "Content-Length" header and forces a chunked download. Of course, this is not required if you are using the intelligent versions of readfile in this article.

A missing Content-Length header implies the following: 1 Your browser will not show a progress bar on downloads because it doesn't know their length 2 If you output anything e. white space after the readfile function by mistake , the browser will add that to the end of the download, resulting in corrupt data.

Clicking a link that points to a PDF or an Image file will not cause it to download to your hard drive directly. It will only open the file in your browser. Further you can save it to your hard drive. However, zip and exe files are downloaded automatically to the hard drive by default. You can force images or other kind of files to download directly to the user's hard drive using the PHP readfile function.

Here we're going to create a simple image gallery that allows users to download the image files from the browser with a single mouse click.
