List CakePHP File Upload error codes

Anyway, can anyone give me the error code definitions for when files are uploaded in cakePHP.

So my $this-data contains something like this,

Array ( [file] => Array ( [name] => cake.jpg [type] => image/jpeg [tmp_name] => /tmp/hp1083.tmp [error] => 1 [size] => 24530 ) )

What does [error] = 1 indicate?

While you开发者_运维问答're at it can you list the break down of all the numbers, then maybe it'll be easier for others to find it the future

Thanks!

File upload has nothing to do with CakePHP.

$this->data contains what $_FILE contains, it is a HTTP/PHP specific array.

Documentation, $_FILE, and the error codes.
