How to sort a multidimensional array with values from multidimensional array?

Question

I am developing a test which will give a result of 2 values

$result = array( 't' => 10, 's' => 20 );

and i have ranges that will give a response as badge name from array to that result:

$badges = array(
    'badge1' => array(
        array('tLow' => 0, 'tHigh' => 20),
        array('sLow' => 0, 'sHigh' => 10)
    ),
    'badge2' => array(
        array('tLow' => 0, 'tHigh' => 10),
        array('sLow' => 11, 'sHigh' => 20)
    ),
    'badge3' => array(
        array('tLow' => 21, 'tHigh' => 30),
        array('sLow' => 0, 'sHigh' => 10)
    ),
    'badge4' => array(
        array('tLow' => 31, 'tHigh' => 40),
        array('sLow' => 0, 'sHigh' => 10)
    ),
    'badge5' => array(
        array('tLow' => 11, 'tHigh' => 30),
        array('sLow' => 11, 'sHigh' => 30)
    ),
    'badge6' => array(
        array('tLow' => 0, 'tHigh' => 10),
        array('sLow' => 21, 'sHigh' => 30)
    ),
    'badge7' => array(
        array('tLow' => 0, 'tHigh' => 10),
        array('sLow' => 31, 'sHigh' => 40)
    ),
);

badge arrays correspond to a grid which looks like this

+---+
| 7 |
+---+---+---+
| 6 |       |
+---+   5   +
| 2 |       |
+---+---+---+---+
|   1   | 3 | 4 |
+---+---+---+---+

so my question is what is the most effective way to get a badge for my result? maybe there is a better approach to this?

i don't think it is language dependent in any way and i am fine with pseudo code. I dont want to filter out people who don't appreciate PHP :) — ShintoTuna

OK - there's a language-agnostic tag for that kind of question, but you should probably use pseudo code if the question is truly language agnostic, as not everyone can read php/perl/whatever. — Paul R

Of the top of my head you could do something like this.

foreach ($badges as $key => $badge)
{
   if ($result['t'] >= $badge[0]['tLow'] && $result['t'] <= $badge[0]['tHigh'])
   {
      // t matches
      if ($result['s'] >= $badge[0]['sLow'] && $result['s'] <= $badge[0]['sHigh'])
      { 
         // s matches
         echo 'Badge was found: '.$key;
         break;
      }
   }
}

This code was not tested. But should work

If you change $badge['tLow'] to $badge[0]['tLow'] and 3 others by same pattern in the if statments it will work fine. Also after echo its wise to put a break; statement so it stops after it finds something. Other than that thanks a lot!
