Laravel download base64 encoded files

Laravel has the ability to stream files from disc and remove them as soon as they've been downloaded. 

This snippet illustrates this ability. This is useful when you have binanry data that needs storing in order to be emailed and then removed afterwards: 

$attachment = EmailAttachment::where('id', $id)->first();
$path       = public_path($attachment->name);
$contents   = base64_decode($attachment->contentBytes);

//store file temporarily
file_put_contents($path, $contents);

//download file and delete it
return response()->download($path)->deleteFileAfterSend(true);

For the past 12 years, I’ve been developing applications for the web using mostly PHP. I do this for a living and love what I do as every day there is something new and exciting to learn.

In my spare time, the web development community is a big part of my life. Whether managing online programming groups and blogs or attending a conference, I find keeping involved helps me stay up to date. This is also my chance to give back to the community that helped me get started, a place I am proud to be apart of.

Besides programming I love spending time with friends and family and can often be found together going out catching the latest movie, staying in playing games on the sofa or planning a trip to someplace I’ve never been before.
