Here's a function that I have used to get a nice simple array of all incoming files from a page. Note that this function loses the file input names I usually process the files just by type. It takes whatever is sent from the browser, so don't trust this for the image type. In checking the error code, you probably ought to check for code 4.

I believe Code 4 means no file was uploaded, and there are many instances where that's perfectly OK. Trivanho Said December 25, at AM. Dilip Said Amit Shee Said Great, This is really helpful for download file using CodeIgniter. Parameters filename The filename being read.

Return Values Returns the number of bytes read from the file on success, or false on failure. Notes Note : readfile will not present any memory issues, even when sending large files, on its own.

Tip A URL can be used as a filename with this function if the fopen wrappers have been enabled. Just a note for those who face problems on names containing spaces e. It does work, but you may encounter memory exhaustion using "fread". 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 avoid the risk of choosing themselves which files to download by messing with the request and doing things like inserting ".. It's your script and you have full control over how it maps file requests to file names, and which requests retrieve which files.

Basic first-day-at-school security principle, that. 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.

Here, the four anchor elements are defined to download the four types of files. Output The following dialog box will appear to download the file after clicking the zip file link. The user can then download the file or open the file in the archive manager.

If you click on the image file, the image will be opened automatically in the browser, as shown in the following output. You must save the file to make a copy of the image file in the local drive. In the same way, when you click on PDF and TEXT file links, the content of the file will be opened in the browser without downloading the file.

The solution to this problem is to download the file forcibly using the built-in PHP readfile function. The readfile function is used in PHP script to forcibly download any file of the current location, or the file with the file path.
