Use three Array elements to hold on to the last A,B or W value. The part after the last _ is the designator. Empty fields get stored in a 4th element array[" "], that never gets printed.. Try something like this..

Hello,
I am trying to parse a file that resembles the last three groupings into something looking like the first two lines. I've fiddled with sed and awk a bit, but can't get anything to work properly. I need them separated by some delimiter. The file is some 23,000 lines of the stuff....

uasort
UASORT(3) 1 UASORT(3)uasort - Sort an array with a user-defined comparison function and maintain index associationSYNOPSIS
bool uasort (array &$array, callable $value_compare_func)
DESCRIPTION
This function sorts an array such that array indices maintain their correlation with the array elements they are associated with, using a
user-defined comparison function.
This is used mainly when sorting associative arrays where the actual element order is significant.
Note
If two members compare as equal, their relative order in the sorted array is undefined.
PARAMETERS
o $array
- The input array.
o $value_compare_func
- See usort(3) and uksort(3) for examples of user-defined comparison functions.
RETURN VALUES
Returns TRUE on success or FALSE on failure.
EXAMPLES
Example #1
Basic uasort(3) example
<?php
// Comparison function
function cmp($a, $b) {
if ($a == $b) {
return 0;
}
return ($a < $b) ? -1 : 1;
}
// Array to be sorted
$array = array('a' => 4, 'b' => 8, 'c' => -1, 'd' => -9, 'e' => 2, 'f' => 5, 'g' => 3, 'h' => -4);
print_r($array);
// Sort and print the resulting array
uasort($array, 'cmp');
print_r($array);
?>
The above example will output:
Array
(
[a] => 4
[b] => 8
[c] => -1
[d] => -9
[e] => 2
[f] => 5
[g] => 3
[h] => -4
)
Array
(
[d] => -9
[h] => -4
[c] => -1
[e] => 2
[g] => 3
[a] => 4
[f] => 5
[b] => 8
)
