Hey ! Thanks for your reply. I couldn't get that piece working. how do i find if my awk supports asort. And can you please explain the code ?
I believe that asort() is only available in gawk (GNU awk). Try executing
which might give you the version. Assuming it's not gawk, then you could implement your own sort. Probably not as efficient as the built-in, but better than nothing. Example below using the original code from CarloM and adding a sort (bubble) function.

asort
ASORT(3) 1 ASORT(3)asort - Sort an array and maintain index associationSYNOPSIS
bool asort (array &$array, [int $sort_flags = SORT_REGULAR])
DESCRIPTION
This function sorts an array such that array indices maintain their correlation with the array elements they are associated with. This is
used mainly when sorting associative arrays where the actual element order is significant.
PARAMETERS
o $array
- The input array.
o $sort_flags
- You may modify the behavior of the sort using the optional parameter $sort_flags, for details see sort(3).
RETURN VALUES
Returns TRUE on success or FALSE on failure.
EXAMPLES
Example #1
asort(3) example
<?php
$fruits = array("d" => "lemon", "a" => "orange", "b" => "banana", "c" => "apple");
asort($fruits);
foreach ($fruits as $key => $val) {
echo "$key = $val
";
}
?>
The above example will output:
c = apple
b = banana
d = lemon
a = orange
The fruits have been sorted in alphabetical order, and the index associated with each element has been maintained.
