PHP Snippet 1:
$a = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10];
$b = ['a', 'b', 'c', 'd', 'e', 'f'];
$c = ['A', 'B'];
PHP Snippet 2:
$args = [$a, $b, $c];
count($args) = 3;
PHP Snippet 3:
$output = [1, 'a', 'A'];
PHP Snippet 4:
$a = [2, 3, 4, 5, 6, 7, 8, 9, 10];
$b = ['b', 'c', 'd', 'e', 'f'];
$c = ['B'];
PHP Snippet 5:

$b = ['c', 'd', 'e', 'f'];
$c = [];
$output = $output = [1, 'a', 'A', 2, 'b', 'B'];
//because $c is empty array_filter() removes it from $args
$args = [$a, $b];
PHP Snippet 6:

),
$a,
$b,

PHP Snippet 7:
$output = [];

foreach ($array as $k => $v) {
$output[$k][$i] = $v;
}
}
var_export(implode(array_merge(...$output)));
