Same function as suggested by tippy2k/jmartin. tippy2k's code seems to have a syntax error in
the function declaration; jmartin's code throws a notice.
So here's yet another version, without temporary variables and loops:
<?
// 1 <= $a <= 702
function col2str($a) {
return
($a-->26?chr(($a/26+25)%26+ord('A')):'').chr($a%26+ord('A'));
}
// Example
$colname = col2str(1) // returns "A"
$colname = col2str(27) // returns "AA"
$colname = col2str(702) // returns "ZZ"
?>
