Hi all,
What do you think is the best way to display string 'abcdef' as
'fedcba'?
$tmp = '';
$str = 'abcdef';
for ($i = strlen($str); $i >= 0; $i--) {
$tmp.= $str[$i];
}
echo $tmp;
Close, but no cigar. $i should be initialised to strlen($str)-1
otherwise you start one character beyond the end of the string.
Ah, well. You're right, but it works none the less.
Just because it works doesn't mean it's right.
