Rest Download File Php Example Function

What Is Function In Php

I’ve seen many download scripts written in PHP, from simple one-liners to dedicated classes. Yet, at least half of them share common errors; in many cases programmers simply copy the code from something that works, without even attempting to understand what it really does.

There is a server class that can retrieve the Web service function being called and the respective parameters from the HTTP request and calls given user defined functions or a class previously registered to handle the Web service.

What follows is not a complete working download script, but rather a set of issues you should be aware about and that will allow you to write better code. Never accept paths as input It’s very tempting to write something like. $path_parts = pathinfo ( $_GET [ 'file' ] ); $file_name = $path_parts [ 'basename' ]; $file_path = '/mysecretpath/'. $file_name; $path_parts = pathinfo($_GET['file']); $file_name = $path_parts['basename']; $file_path = '/mysecretpath/'.

Even better would be to accept only numeric IDs and get the file path and name from a database (or even a text file or key=>value array if it’s something that doesn’t change often).

Anything is better than blindly accept requests. If you need to restrict access to a file, you should generate encrypted, one-time IDs, so you can be sure a generated path can be used only once. Use headers correctly This is a very widespread problem and unfortunately even the PHP manual is plagued with errors. Developers usually say “this works for me” and they copy stuff they don’t fully understand.

First of all, I notice the use of headers like Content-Description and Content-Transfer-Encoding. Hp Lj 1150 Service Manual here. There is no such thing in HTTP. Don’t believe me? Have a look at, they specifically state “ HTTP, unlike MIME, does not use Content-Transfer-Encoding, and does use Transfer-Encoding and Content-Encoding“. You may add those headers if you want, but they do absolutely nothing.

Sadly, this wrong example is present even in the PHP manual. Second, regarding the MIME-type, I often see things like Content-Type: application/force-download. There’s no such thing and Content-Type: application/octet-stream (RFC1521) would work just as fine (or maybe application/x-msdownload if it’s an exe/dll). If you’re thinking about Internet Explorer, it’s even better to specify it clearly rather than force it to “sniff” the content. See for details. Even worse, I see these kinds of statements.

Header ( 'Content-Type: application/force-download' ); header ( 'Content-Type: application/octet-stream' ); header ( 'Content-Type: application/download' ); header('Content-Type: application/force-download'); header('Content-Type: application/octet-stream'); header('Content-Type: application/download'); The author must have been really frustrated and added three Content-Type headers. The only problem is, as specified in the manual entry, “ The optional replace parameter indicates whether the header should replace a previous similar header, or add a second header of the same type.

By default it will replace“. So unless you specify header('Content-Type: some-value', FALSE), the new Content-Type header will replace the old one. Forcing download and Internet Explorer bugs What would it be like to not having to worry about old versions of Internet Explorer? A better world, that’s for sure. To force a file to download, the correct way is.
