How to substitute a character for another one

[francescomoi]

Hi.

I want to substitute a character (e.g. 'R') for another one ('-R')
within a
word: 'RECORD' ---> '-RECO-RD'

Is it possible by using any PHP command? Regards.

<?

$i = "record";

$x = str_replace("r", "-r", $i); // looks through i for r's, replaces
them with -r's

echo $x;

?>

that should work.
