In a for loop, I receive an array like that:

array(1) { [0]=> array(1) { [0]=> string(1) "4" } } 

array(1) { [0]=> array(2) { [0]=> string(1) "3" [1]=> string(1) "4" } }

array(1) { [0]=> array(7) { [0]=> string(1) "1" [1]=> string(1) "2" [2]=> string(2) "30" [3]=> string(2) "43" [4]=> string(2) "65" [5]=> string(2) "53" [6]=> string(3) "634" } }

I need implode that values with "-", my desired output isa string:

4

3-4

2-30-43-65-53-634
