Unserialize serialized data in wp_options

    I need to extract the data saved in my widgets from wp_options for comparisons and other uses. As far as I understand the data needs to be un-serialized and that is the function of get_option().

    But I can’t seem to do anything with the data.

    The following code seems simple enough:

    $text_widgets = get_option( 'widget_suidlanders_advertensies' );
	echo var_dump($text_widgets);

	foreach ( $text_widgets as $widget ) {
		extract( $widget );
}

    The var_dump() throws out the following:

    array (size=2)
  2 =>
    array (size=3)
      'title' => string 'Titel' (length=5)
      'text' => string 'Teks' (length=4)
      'textarea' => string 'Teks Area is hier		' (length=19)
  '_multiwidget' => int 1

    How am I suppose to utilize this to make a comparison? If ($this == $that) etc.

    get_option() unserializes the data for you, as is evidenced by var_dump outputting an array and not a string. The array with title, text, textarea will be in one of the $widget instances inside the loop. When you extract that array, it is equivalent to this:

    $title = 'Titel';
$text = 'Teks';
$textarea = 'Teks Area is hier		';

    So to do a comparison inside the loop after $widget is extracted, you just do something like this:
    if ('Titel' == $title ) echo 'Titel found in title!';

    That was a big help in pushing me in the right direction. Thank you!!

    After reading up a bit more I assigned the values to variables like so.

    foreach ( $text_widgets as $widget => $value) {
$title = $value['title'];
}

    and now I can work the rest of my magic!
