Because he wants to change every *other* comma into a semi-colon (i.e.
change the second, fourth etc).
Your function would change *every* comma into a semi-colon.
I don't think you can easily do it with regex as you can't really
differentiate between comma's.
I would suggest something along the lines of:
$array = explode ( ', ', $string );
$arraycount = count($array);
$new_string = '';
for( $i=0; $i<$arraycount; $i++; ) {
if ((1&$i)) {
//$i is odd
$new_string .= $array[$i] . ', ';
}
elseif (!(1&$num)) {
//$i is even
$new_string .= $array[$i] . '; ';
}
}
$string = $new_string;
unset($new_string);
Hope this helps,
Juliette
