如何回显stdClass对象数组的数组值

Question

I have an array within an STDClass object as my select options. I cannot understand how to echo its values.

var $fields = array( array(
   'name'   => 'icon',
   'type'   => 'select',
   'items' => array(0 => 'news', 1 => 'technology', 2 => 'products'),
    ),  
);

Then within the widget function:

function widget($args, $instance)
{
$inst = (object) wp_parse_args($instance, array(
        'icon'              => '',
        'title'             => '',
        'display_title'     => '',
        'content'           => '',
        'link_text'         => '',
    ));
}

Within this function echo $inst->icon; gives me the key. How do I get the value?

Answer 1

Have you tried the 'old' array notation instead of the arrow?

echo $inst['icon'] ;

Source : that is how they seem to print values in this documentation : http://codex.wordpress.org/Function_Reference/wp_parse_args
