Question

I have a form which includes 3 date of birth inputs like the following:

  <label>Date of Birth</label>
  <input type='text' size='2' maxlength='2' name='DOB[2]' />
  <input type='text' size='2' maxlength='2' name='DOB[3]' />
  <input type='text' size='4' maxlength='4' name='DOB[1]' />

The order of the inputs work as month/day/year. I am sending this to my script which then implodes the DOB array like such (Thanks to @Matt H.):

if(isset($_userData['DOB']))
    $_userData['DOB'] = implode('-', $_userData['DOB']);

Now, the problem is, this implodes it to the improper format of month/day/year, which is not the order of the array I set, but the order of the inputs. Am I stuck with having to manually concatenate the array into the format I need for MySQL (year/month/day) ?

Try:

if(isset($_userData['DOB'])){
    ksort($_userData['DOB']);
    $_userData['DOB'] = implode('-', $_userData['DOB']);
}

This will sort the array $_userData['DOB'] by key. Based on your input elements, it is going to become:

$_userData['DOB'] = array(
    1 => 'YYYY',
    2 => 'MM',
    3 => 'DD'
);
