Question

I have some variables returned from get_defined_vars() and I need to map two subsets of data together to form a flat associative array.

Input:

[
    'lead' => [
        2 => 'fstory',
        4 => 'him',
        5 => 'trtr',
        1 => '508b38ee02f502.23680245.png',
    ],
    'form' => [
        'id' => 3,
    ],
    'fields' => [
        [
            'adminLabel' => 'formname',
            'id' => 2,
        ],
        [
            'adminLabel' => 'hisher',
            'id' => 4,
        ],
        [
            'adminLabel' => 'fname',
            'id' => 5,
        ],
        [
            'adminLabel' => 'sign',
            'id' => 1,
        ]
    ]
]

I need to the [fields][adminLabel] elements to become keys and the [lead][#] elements to be the values.

Desired result:

[
    'formname' => 'fstory'
    'fname' => 'trtr'
    'hisher' => 'his'
    'sign' => '508b38ee02f502.23680245.png',
]

Answer 1

Try this. It is untested.

$result_values  = $array['lead'];
$results        = array();
foreach ($array['form']['fields'] as $value) {
  if (is_array($value)) {
    $results[$value['adminLabel']] = $result_values[$value['id']];
  }  
}
print_r($results);
