How can I use PHP closure function like function() use() on PHP 5.2 version?

Question

How can I use PHP closure function like function() use() on PHP 5.2 version as it has no support for anonymous functions?

Currently my code is something like below

I assume you are asking for the 'use' directive due to the early value bindings, right? You could use 'create function' and insert there some static variables with the values you have at the creation time, for example

$code = '

static $taxonomy_name = "'.$taxonomy_name.'";
static $plural = "'.$plural.'";
static $post_type_name = "'.$post_type_name.'";
static $options = json_decode("'.json_encode($options).'");

$options = array_merge(
    array(
         "hierarchical" => false,
         "label" => $taxonomy_name,
         "singular_label" => $plural,
         "show_ui" => true,
         "query_var" => true,
         "rewrite" => array("slug" => strtolower($taxonomy_name))
    ),
    $options
);

// name of taxonomy, associated post type, options
register_taxonomy(strtolower($taxonomy_name), $post_type_name, $options);
            ';

$func = create_function('', $code);
