Reduce not work correctly i need add exeption / exlusion

i have an array like that in $_POST var; but need know that in some cases the array is a hugge multilevel from json:

array (
  'idprocess' => 'f-gen-dato1',
  'idform' => 'f-gen-dato2',
)

OR:

array (
  array (
    'idprocess1' => 'f-gen-dato1',
    'idform1' => 'f-gen-dato2',
  ),
  array (
    'idprocess2' => 'f-gen-dato1',
    'idform2' => 'f-gen-dato2',
  )
)

i try to reduce; any arrays with this:

public function ReduARR($Var) {
        $result = $Var;
        if (is_array($Var)) {
            $result = array_reduce($Var, 'array_merge', array());
        }
        return $result;
    }

but i need avoid the array i show you... frist or single level. and work only in the second or multilevel.

i get this error with one lvl:

array_merge(): Argument #2 is not an array

Solution

My guess is that you wish to merge or reduce some arrays, and you might be trying to write some functions similar to:

$arr1 = array(
    'idprocess1' => 'f-gen-dato1',
    'idform1' => 'f-gen-dato2',
);

$arr2 = array(
    'idprocess2' => 'f-gen-dato1',
    'idform2' => 'f-gen-dato2',
);

function finalArray($arr1, $arr2)
{
    if (is_array($arr1) && is_array($arr2)) {
        return mergeTwoArrays($arr1, $arr2);
    }
}

function mergeTwoArrays($arr1, $arr2)
{
    return array_merge($arr1, $arr2);
}

var_dump(finalArray($arr1, $arr2));

for instance.

$arr = array(
    array(
        'idprocess1' => 'f-gen-dato1',
        'idform1' => 'f-gen-dato2',
    ),
    array(
        'idprocess2' => 'f-gen-dato1',
        'idform2' => 'f-gen-dato2',
    ),
);

if (is_array($arr[0]) && is_array($arr[1])) {
    var_dump(array_merge($arr[0], $arr[1]));
}

Output

array(4) {
  ["idprocess1"]=>
  string(11) "f-gen-dato1"
  ["idform1"]=>
  string(11) "f-gen-dato2"
  ["idprocess2"]=>
  string(11) "f-gen-dato1"
  ["idform2"]=>
  string(11) "f-gen-dato2"
}
