PHP reverse the order of sub array

Question

Here is an array example I have.

Array
(
    [0] => Array
        (
            [0] => a
            [1] => b
            [2] => c
        )

)

I need the order of the sub array to be reversed. I know the function I need to use is "reverse_array" but I do not know how to apply it to an array within an array.

Answer 1

The function you need to use is array_reverse() , but I'm assuming that's the one you were talking about. To answer your question, you simply specify the array item instead of the main array:

$array[0] = array_reverse($array[0]);
//     ^                         ^

---

If you instead wish to reverse all sub-arrays in an array, you can use array_map() :

$array = array_map('array_reverse', $array);

Answer 2

use this

array_reverse($array[0]);

or use

$newSortedArray=array();
foreach ($array as $arr){
  $newSortedArray= array_reverse($arr);
}

echo "<pre>";
print_r($newSortedArray);
