Sorry... a little correction:

<?php

$data="## /T (KEY1)/V (VALUE1)|| ## /T (KEY2)/V (VALUE2)|| ## /V 
(VALUE3)/T (KEY3)||";

$data_array=array();
preg_replace(
    array(
    "/\#\#\s*\/T\s*\(([^\)]*)\)\s*\/V\s*\(([^\)]*)\)\s*\|\|/e",
    "/\#\#\s*\/V\s*\(([^\)]*)\)\s*\/T\s*\(([^\)]*)\)\s*\|\|/e"
    ),
    array(
    "\$data_array['\\1']='\\2';",
    "\$data_array['\\2']='\\1';"
    ),
    $data
);

print_r($data_array);  //see if you get it as expected

?>
