Comment (by anmari):

 get_posts also NOT case sensitive:


 {{{
         $args = array(
         'posts_per_page' => '-1',
         'post_type'=>'any',
         'meta_key'=> $key  // update to your key
 );
         $allpostwith = get_posts( $args );
 }}}


 will return a MIX of lower and uppercase.


 Is it caused by a mysql 'feature' perhaps?  Similar behaviour in
 phpmyadmin?  by why get_post_meta works ie is case sensitive  ?
