Answer 1

To make it more applicable, Demo
$a = array('a','b','c','d','e','f');
$input = array('ina', 'inb','inc');
$loop = 1;
$input_length = count($input); // TODO process the length with 0 case.
foreach($a as $index => $value){
if(!($i = $index % $input_length)){
echo $loop . PHP_EOL;
$loop++;
}
echo $value . "_" . $input[$i] . PHP_EOL;
}

You're keeping a few variables that you don't really need as they can be derived from the $key value from $a. To get the output you want, you could do this:
$a = array('a','b','c','d','e','f');
$b = array('1','2');
$input = array('ina', 'inb','inc');
$len = count($input);
foreach ($a as $key => $v) {
$idx = $key % $len;
if ($idx == 0){
echo $b[floor($key/3)] . PHP_EOL;
}
echo $v . "-";
echo $input[$idx] . PHP_EOL;
}
Output:
1
a-ina
b-inb
c-inc
2
d-ina
e-inb
f-inc
