Here i have a array in that i need to assign both Display Name and Database Value to def_value key. how to do that can anyone please help me..

Answer 1

Your way is incorrect as the second index will override the first index value because they have the same name. So You will have only this in your array:

$def_field = array(
    "def_value" => 'Database Value'
);

You can do it these ways

$def_field = array(
  "def_value" => array('Display Name','Database Value')
);

Or like this:

$def_field = [];
$def_field['def_value'][] = 'Display Name';
$def_field['def_value'][] = 'Database Value';

The second exemple kind of explains everything. You will create an array with index $def_value inside array $def_field with values 'Display Name' having index 0 and 'Database Value' having index 1 .

Answer 2

You will probably need to add it as a nested array like this:

$def_field = array(
    "def_value" => array('Display Name','Database Value')
);
