Q: How to get the value of a checkbox of which name without '[]'?

[Dallas Thunder]

Consider the following form in a HTML file:

....
<input type=checkbox name="box" value=1>
<input type=checkbox name="box" value=2>
<input type=checkbox name="box" value=3>
<input type=checkbox name="box" value=4>
....

Now I'm posting this form into a PHP script. The problem is I can't change
that HTML file. Which means I can't modify the code above into PHP prefered
style:

<input type=checkbox name="box[]" value=1>
<input type=checkbox name="box[]" value=2>
....

So, how can I get the correct values of the checkbox? $_REQUEST['box'] is
not an array and only contains the last value. Thanks!

You can try using $HTTP_RAW_POST_DATA and parsing it yourself - or grab
the get value directly from $_SERVER['QUERY_STRING']

Why is this the preferred style, and where can I read more about it?

I don't know about preferred style or not, but if you want PHP to recognize
multiple values from a form or URL, then you must add the [] onto the name
so PHP will put it into an array. Otherwise you end up with
"box=1&box=2&box=3" and when PHP parses that, each overwrites the other, so
you end up with $box == 3 at the end and the other values are lost. I'm sure
it's discussed in the Form Handling section of the manual.
