Why title_li =” not working

I want to hide the ‘Categories’ and used the following code

<?php
                    $args = array(
                        'parent'            => 33, 
                        'show_count'        => 1,
                        'title_li='         => __( '' ),
                        'hide_empty'        => 0,
                    );
                    wp_list_categories($args)
                    ?>

But it is not working, why? Thank you.

Method 1

Because the parameter name is title_li and not title_li=. It also doesn’t make sense of using __( '' ), so I’d change that to just ''.

// When the args is a query string, title_li= works.
$args = 'title_li=';

// But when the args is an array, use just title_li.
$args = array(
    'title_li=' => '', // bad
    'title_li'  => '', // good
);
