How to save array data in wp_options table

Paula

I would like to add an array of data to the wp_options table. I am aware of the update_option() function, but I only found the saving single value with the update_option() function.

This is where I found some code of the example, but I can't convert it to add array data.

Let I try to explain through example. Let's start to add single value and this is how you can do it.

update_option( 'my_data', 'my_value' );

Like the my_value you can pass the array variable. Consider with the next example.

$data = array();

$data['my_key_1'] = 'my_value_1';
$data['my_key_2'] = 'my_value_2';

update_option( 'my_data', $data );
