I'm stuck in logic.. Kindly help

Thanks in advance

Current Produced array :

        Array
        (
         [5316] => Array
                (
                  [0] => Array
                  (
                       [PROD1] => color=black
                  )

                  [1] => Array
                  (
                   [PROD1] => paper=a1
                  )

                  [2] => Array
                  (
                   [PROD2] => color=metallic_silver
                  )

                  [3] => Array
                  (
                   [PROD2] => paper=a1
                  )
                )
        )

I want to convert this array into this form

Array
        (
         [5316] => Array
         (
          [PROD1] => Array
          (
           color => black
           paper => a1
          )
          [PROD2] => Array
          (
           color => metallic_silver
           paper => a1
          )
         )
        )

If you can't hardcode that key to directly point to it, you can use reset() in this case, then grouped them inside a foreach accordingly. Example:

$array = array(
    5316 => array(
        array('PROD1' => 'color=black'),
        array('PROD1' => 'paper=a1'),
        array('PROD2' => 'color=metallic_silver'),
        array('PROD2' => 'paper=a1'),
    ),
);

$grouped = array();
// point it to the first key which gives an array of those values
foreach (reset($array) as $key => $value) {
    reset($value); // reset the internal pointer of the sub array
    $key = key($value); // this return `PROD1, PROD2`
    $grouped[$key][] = current($value); // current gives color=black, the values
}

$array[key($array)] = $grouped; // then reassign

echo '<pre>';
print_r($array);
