You could easily execute a serialize() function on a form that wraps these checkboxes. The resulting string can be "decoded" in php using the parse_str() function.

A serialized string of all checkboxes being selected would look like this:

valor%5B%5D=1&valor%5B%5D=2&valor%5B%5D=3&valor%5B%5D=4&valor%5B%5D=5&valor%5B%5D=6

Passing that value though parse_str() will give you something similar to this:

[valor] => Array
    (
        [0] => 1
        [1] => 2
        [2] => 3
        [3] => 4
        [4] => 5
        [5] => 6
    )
