Hello,
i have a string looking like this.
 

## /T (KEY1)/V (VALUE1)|| ## /T (KEY2)/V (VALUE2)|| ## /V (VALUE3)/T
(KEY3)||
 

 

I know want to separete it in to keys and values and insert them into an
array.
Note that /T always shows that teh upcoming value in() is a Key and 
that /V
always is a Value. And that the set can be flipped.

 

Thank you very much for helping.

It seems you complex yourself too much.. ;)
Try using regexp with the 'e' modifier:
<?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
?>
I believe there's an easier way to store your data as strings (like 
serialize), so why not using them?!
see alse: http://www.php.net/serialize
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
?>
