Question

When you do the following in an HTML form:

<input name='one[]' value='foo' /> <input name='one[]' value='bar' /> <input name='two[key]' value='something' /> 

and submit the form to a PHP page, The $_POST array will look as follows:

array(     'one' => array(         0 => 'foo',         1 => 'bar'     ),     'two' => array(         'key' => 'something'     ), ), 

If you look at the header data, though, it will look as follows:

one[]=foo&one[]=bar&two[key]=something 

Does anyone have a script with which to convert the PHP array back into the POST data string? urlencode doesn’t work as it can’t acces arrays…
