is there a way to convert chess moves to PGN??

[leelong]

i mean converting chess moves like e1-g1 to PGN format of O-O(castling).

i'd searched many hours but all i got were PGN parser and draw the borad. this is not what i am looking for.

what i really mean is a PHP function/class to convert for example "white knight move" -- "B1C3" into PGN format "Nc3"

thank you!!

Sorry, I cannot help you other than to ask if you looked in google code.

chess lang:php

that isn't a PHP code... 'pgn' =>'application/x-chess-pgn' looks more like a header.

i am looking for function/script like

$coordinate = 'A2A3 B1C3';
function convert_pgn($coordinate){....return $pgn_notation;}

actually i am referring to a PHP Chess class at http://www.phpclasses.org/browse/file/8351.html

at line 2050:--
$coordinate = $this->valueOfX($x_start) . $y_start . $this->valueOfX($x_end) . $y_end;

the above will show coordinate notation like "B1C3" rather than PGN format "Nc3"

i need a way to convert $coordinate into PGN instead

Have you considered writing your own converter? I don't imagine it to be too hard.

Probably the biggest problem with the conversion you are trying to do is that you want to convert from a notation that just identifies the start and end positions of a move to a notation that needs to know what piece it is that is being moved.
