Generate a new array from another array

[Omzy]

public function getEventTypes()
{
  return array(
   1=>array('Exhibition', 1),
   2=>array('Wedding', 1),
   3=>array('Business', 1),
   4=>array('School Trip', 0),
   5=>array('Birthday', 0),
   6=>array('Concert', 1),
   7=>array('Sporting Event', 1),
   8=>array('Training', 0),
   9=>array('Conference', 1),
   10=>array('Other', 1),
  );
}

 

I now want to generate a new array from this array as follows:

 

1) must retain the existing key

2) must be single dimensional and the value of each element will be value[0]

3) must only contain the array elements where value[1] = 1

 

So for example the generated array should be as follows:

 

 
public function getActiveEventTypes()
{
  return array(
   1=>'Exhibition',
   2=>'Wedding',
   3=>'Business',
   6=>'Concert',
   7=>'Sporting Event',
   9=>'Conference',
   10=>'Other',
  );
}

Something like this would work:

<?php
function af($ary) {
   $na = array();
   if (!is_array($ary)) {
     return (false);
   }
   foreach($ary as $k=>$e) {
      if ($e[1]) {
         $na[$k] = $e[0];
      }
   }
   return($na);
}
$orig = array(
   1=>array('Exhibition', 1),
   2=>array('Wedding', 1),
   3=>array('Business', 1),
   4=>array('School Trip', 0),
   5=>array('Birthday', 0),
   6=>array('Concert', 1),
   7=>array('Sporting Event', 1),
   8=>array('Training', 0),
   9=>array('Conference', 1),
   10=>array('Other', 1),
  );
$new = af($orig);
print_r($new);
?>
