while (preg_match($pat,$txt,$matches) > 0) {
print "$txt\n";
printf("[0]: <%s>\n",$matches[0]);

printf("[2]: <%s>\n",$matches[2]);
preg_replace($pat,$rpl,$txt);
}
The prints are for debugging. $matches contains what I expect but
nothing gets replaced and $txt stays the same so it loops forever.
What am I doing wrong?
Maybe this
<?php
$txt = 'A promise is a debt. -- Irish Proverb';
$parts = explode('--', $txt, 2);
$parts[1] = str_replace(' ', ' ', $parts[1]);
echo join('--', $parts);
?>
