Just pass the array as the second argument to update_option - WordPress will serialize the value before storing it in the database, and automatically unserialize it when you read it:

update_option( 'meow', array(
    'cats' => '2',
    'food' => array( 'tona', 'fish' ),
) );

$meow = get_option( 'meow' );

print_r( $meow );

// Array
// (
//     [cats] => 2
//     [food] => Array
//         (
//             [0] => tona
//             [1] => fish
//         )
// )
  • thank you for answer, I tried the code but i have got Error: Warning: Illegal offset type in isset or empty in C:\myweb\wp-includes\option.php on line and Notice: Array to string conversion in C:\myweb \wp-includes\option.php on line AND Notice: Array to string conversion in C:\Mywebwp-includes\formatting.php on line
