[wp-hackers] categories with no childs

[Dion Hulse (dd32)]

I've seen a few inefficient routines suggested so far, So heres a much  
simpler one which definately works in WordPress 3.0, And i believe should  
work in 2.9 as well:


$terms_with_children = array_keys( get_option('category_children') ); //  
Use the Option cache of the hierarchy to retrieve terms which have children
$terms_Without_children = get_terms('category', array('hide_empty' =>  
false, 'parent' => '0', 'exclude' => $terms_with_children )); // Fetch  
terms with a Parent of 0 (ie. top level), which are not in the list of  
terms with known children

var_Dump($terms_Without_children);

Cheers
