OK, you want to argue with everyone who supports the idea of macros. Fine.
Let's see you to this as easily and as cleanly without macros:

define('FOREACH(X, K, V)', 'if (isset(X) && isarray(X)) foreach(X as K=>V)


FOREACH($var,$key,$value) {

// Process data in $key=>$value here.
}

FOREACH($var2, $key2, $value2) {
// Different processing of $key2=>value2 here
}
