Question #1:
What happens when your KEY or VALUE contains "##", "/T", or "/V"
Depending on your answer to that, the best solution will change a bit.

In the short term:

$string = "## /T (KEY1)/V (VALUE1)|| ## /T (KEY2)/V (VALUE2)|| ## /V
(VALUE3)/T (KEY3)|| ";
$keyvalues = explode("##", $string);
$answer = array();
while (list(, $keyvalue) = each($keyvalues)){
$keyvalue = trim($keyvalue);
if (substr($keyvalue, 0, -2) != '||'){
die("Unexpected keyvalue: $keyvalue");
}
$keyvalue = substr($keyvalue, 0, -2);
preg_match("#/T(.*)(/V|$)#", $keyvalue, $key);
$key = $key[1];
preg_match("#/V(.*)(/T|$)#", $keyvalue, $value);
$value = $value[1];
$answer[$key] = $value;
}
