Question

Assuming there are 5 inputs in web form

<input name='the_same[]' value='different' />
<input name='the_same[]' value='different' />
<input name='the_same[]' value='different' />
<input name='the_same[]' value='different' />
<input name='the_same[]' value='different' />

When server side receive the post data, i use a foreach to accept data, say

$the_same = new array();
foreach($_POST['the_same'] as $data)
    $the_same[] = $data;

Will the order of data saved in server side be the same to it in web form? and cross browsers, it could be a criteria all browsers follow.

Answer 1

Well, the W3C recommendation on HTML forms does say:

The control names/values are listed in
the order they appear in the document.

Still, I’d consider it a bit risky to have your app depend critically on that detail.
