how to store a array in option and get array value

To store an array using the WordPress add_option() function, you can serialize the array and then pass it as a string. Here's an example:

// Create an array to store
$my_array = array( 'key1' => 'value1', 'key2' => 'value2', 'key3' => 'value3' );
$serialized_array = serialize($my_array); // Serialize the array
// Store the serialized array using the
add_option function add_option('my_option_name', $serialized_array);

To retrieve the array from the option, you can use the get_option() function and then unserialize the value. Here's an example:

// Retrieve the serialized array from the option
$serialized_array = get_option('my_option_name');
// Unserialize the array
$my_array = unserialize($serialized_array); // Access the values in the array
echo $my_array['key1']; // Output: value1
echo $my_array['key2']; // Output: value2
echo $my_array['key3']; // Output: value3
Note that it's important to sanitize and validate the data before storing it in the database. You can use WordPress functions such as sanitize_text_field() or wp_kses_post() to sanitize and validate the data before storing it in the option.
