PHP, allow visitor to download image that is not on your server

 We posted web development guide with the information on how to save remote images from the web using PHP, and one of the web developers asked us a question on how you can allow people to download the image without saving it on the server, and here is the answer to this question.

Here is the link to the previous post: http://superiorwebsys.com/84-php-how-to-save-image-from-web-remote-image/

Here is the very simple code that will allow you to do so:

header("Content-Type: application/force-download");
header("Content-Disposition: attachment; filename=\"QR.jpg\";" );
header("Content-Transfer-Encoding: binary");

 Click here to run thgis code

In place of $remoteFile you can put a link to any file and this script will force user browser to offer downloading of the content instead of opening it .

I tried your code by just copy and paste but it wont work. The image file is generated but without any QR code. but when I tried your demo it works. Is there something else that you missed out in this tutorial?

Hello Roger,
I just tried that code again and it did work fine for me. Do you get any warnings?

Hi Michael,
I do not get any warning & even I get to download the QR.jpg. But when I try to open, it cannot. The downloaded file size is 130 bytes; no matter what `chl` parameter i provide

Hello Michael,
I have got the code working. Don`t know the reason why it was not working but at last got it working. First used CURL to get the image saved on a server space and then did the download part. Would have shared the code here but don`t know if you would permit that. :)
Thanks for all the support.

Hello Roger,
I`m glad you were able to figure out the problem. You can share the code if you want here, and we will modify styles so it looks like a code.
Thank You!
