Serialize data for wp options

Question

I am creating my first ever plugin, its purpose is to show a notice when some conditions are met, I created the function in jQuery and initially I had to manually edit the file everytime I wanted to change the notice message, so I decided to create a settings page so that the user could edit the message from the front end.

Thanks to another member on stackxchange I was able to use wp localize to show the custom message saved in the wp options instead. however, I now find my self having to structure the message being shown such as;

Title

Message

Image

I don't want to create many options so I thought I could try and serialize the data but I dont know how to.

In the settings page I have a single textbox for the user to enter the message.

<textarea name="msg_data" id="msg_data" cols="40" rows="10" />
<?php echo get_option('notice_data'); ?>
</textarea>

Here is the localize

$custom_notice = get_option('notice_data', 'default_value');
  wp_localize_script( 'lu_ban', 'custom_notice', $custom_notice);

My goal is to create three different inputs, one for title, one for body message and one for image path, can anyone help me out please.

THanks

To store Data use this Code : save the serialize values

$title    = 'Your Title Value';
$message  = 'Your message HTML..';
$image    = 'http://www.domain.com/yourimage.jpg';

$notice_data = array('title'   => $title, 
                     'message' => $message,
                     'image'   => $image
                    );


if(get_option('notice_data') === FALSE){
    add_option('notice_data',  $notice_data );
}else{
    update_option('notice_data', $notice_data );
}

Now you can get the serialize values and use in your code

$notice_data =   get_option('notice_data')  ;  

echo $notice_data['title'];

var_dump($notice_data);
