[FIXED] How to base64 encode a $_FILES file on a form post?

Issue

How can I base64 encode a file sent from one page to another via a form POST.

The following do not work:

• base64_encode($_FILES['file'])
• base64_encode(file_get_contents($_FILES['file']))
• base64_encode(file_get_contents($_FILES['file']['name']))

Why don't they work?

What is the correct thing to do to base64 encode the file?

Solution

tmp_name is the file path to the file that is being temporarily stored

base64_encode(file_get_contents($_FILES['file']['tmp_name']))
