I am wanting to compare two things: the information from the $_POST and
my existing data in $olddata -> this is an array obviously.
I always forget how to use this foreach inside one another.
I want to check $_POST['fname'] against $olddata['fname'] and if they
are the same, for simple testing I want to print out SAME and
if different, DIFFERENT.
foreach ($_POST as $nkey => $new){
foreach($olddata as $okey => $old) {
if ($new == $old) {
print '"'.$new.'" AND "'.$old.'" are the <b
style="color:red">SAME</b>; Next... <br />';
} else {
print '"'.$new.'" AND "'.$old.'" are the
<b>DIFFERENT</b>; Next... <br />';
}
}
}
