try

$a = array('a1' => 1, 'a2' => 2);
$b = array('b1' => 11, 'b2' => 22, 'c2' => 33);

$keys = array_map(null, array_keys($a), array_keys($b));

foreach($keys as $k) {
list($k1, $k2) = $k;
$v1 = isset($k1) ? $a[$k1] : null;
$v2 = isset($k2) ? $b[$k2] : null;
echo "$k1 - $v1 - $k2 - $v2 \n";
}

if you don't need keys, this can be simplified to

foreach(array_map(null, $a, $b) as $v) {
list($v1, $v2) = $v;
echo "$v1 - $v2 \n";
}
