Question

Should I use php serialization?

Is there a limit of file size to serialize? JPGs can go up to 10mb.

Answer 1

PHP sessions are limited by the memory usage limit of PHP. So 10mb would probably be ok, but…

I don’t think “session” is the correct choice to store a large binary data. Uploaded files goes to a temporary folder on the server and you can reach them for a while from that directory. So, if you need to reach that file later, you can simply store the temporary file path to the session.

Example code:

session_start();
$_SESSION["uploaded_file"] = $_FILES["file"];

Then, when you need to copy that file to the real path, you can do something like:

move_uploaded_file($_SESSION["uploaded_file"]["tmp_name"], "images/".$_SESSION["uploaded_file"]["name"]);

You can also reach “type”, “size” and “error” items from $_SESSION[“uploaded_file”] if you need them.
