I have data like this :

array: [
   0: [
     0: {fruits: "apple", price: "15000"},
     1: {fruits: "orange", price: "12000"},
   ],
   1: [
     0: {fruits: "grape", price: "13000"},
     1: {fruits: "chery", price: "14000"},
     2: {fruits: "longan", price: "12000"},
   ],
   2: [
     0: {fruits: "manggo", price: "16000"},
     1: {fruits: "dragon fruit", price: "17000"},
     2: {fruits: "avocado", price: "18000"},
     3: {fruits: "coconut", price: "19000"},
   ],
]

I wanna ask how to know the length of the second data, I already try using nested loop but the result is not same with my expectation my data come like this :

array: [
  0: {fruits: "apple", price: "15000"},
  1: {fruits: "orange", price: "12000"},
  2: {fruits: "grape", price: "13000"},
  3: {fruits: "chery", price: "14000"},
  4: {fruits: "longan", price: "12000"},
  5: {fruits: "manggo", price: "16000"},
  6: {fruits: "dragon fruit", price: "17000"},
  7: {fruits: "avocado", price: "18000"},
  8: {fruits: "coconut", price: "19000"},
]

You can use array_map (which in this case is more than sufficient enough):

array_map('count', $fruits)

If you prefer you can use the Collection methods to help get your count from each "group":

collect($fruits)->map(fn ($i) => count($i))->all()

Or shorter:

collect($fruits)->map('count')->all()

We create a Collection from the array and use the map method to iterate through each "group" (element of that array) and return the count of the "group". Then to get the array from the Collection, all.
