>From the manual at www.php.net. This is a lot more sophiticated than mine
and apparantly works. So as a recent user of PHP, I'm at a loss as to what
is and what isn't.
Using switch would be more efficiant as it would stop once a match is made
(if you use break), but with eleif statements each one is evaluated in
order.
$chr = substr($a,$i,1);
switch (TRUE) {
case $chr == "�" || $chr == "�" || $chr == "�" || $chr == "�":
$a = str_replace(substr($a,$i,1),"a",$a);
break;
case $chr == "�" || $chr == "�" || $chr == "�":
$a = str_replace(substr($a,$i,1),"e",$a);
break;
}
