Question

How do you convert an array in PHP that looks like this:

Array ( 
      [2] => B.eot
      [3] => B.ttf
      [4] => CarnevaleeFreakshow.ttf
      [5] => CarnevaleeFreakshow.eot
      [6] => TRASHED.ttf
      [7] => sub.ttf
      ) 

To look like this:

Array(
     [B]=>array(
               [0] => B.eot
               [1] => B.ttf
               )
     [CarnevaleeFreakshow]=>array(
               [0] => CarnevaleeFreakshow.ttf
               [1] => CarnevaleeFreakshow.eot
               )
     [TRASHED]=>array(
               [0] => TRASHED.ttf
               )
     [sub]=>array(
               [0] => sub.ttf
               )
     )

Is there a name for doing something like this?
the data is being retrieved from a

 scandir

array.

<?php

$data = array ( 
  2 => 'B.eot',
  3 => 'B.ttf',
  4 => 'CarnevaleeFreakshow.ttf',
  5 => 'CarnevaleeFreakshow.eot',
  6 => 'TRASHED.ttf',
  7 => 'sub.ttf'
 ); 

$new_data = array();
foreach ( $data as $value ) {
    $tmp = explode( '.', $value );
    $ext = '';
    if ( $tmp[1] ) $ext = '.' . $tmp[1];
    $new_data[ $tmp[0] ][] = $tmp[0] . $ext;
}

print_r( $new_data );

?>
