# Taxonomy anomaly

 * I am making wordpress posts programmatically with multiple taxonomies.
    There
   is a mix of hierarchical and flat taxonomies.
 * For the hierarchical taxonomy I am using the taxonomy id via a “term_exists” 
   query.
    NO PROBLEM.
 * But along the way I converted one taxonomy from flat to hierarchical and forgot
   to switch from using the string of the term to the ID and it still worked.
    BEFORE
   I proceed, please note I have read in the codex that this is NOT recommended 
   and why, but I have no name conflicts.
 * The problem I am having is when I use “get_the_term_list” to retrieve that taxonomy
   to combine it with a current date and convert it to a hash tag for twitter.
 * First I explode the term list into an array.
    Then I loop though the array with
   a foreach. First I combine the foreach variable with the date. NO PROBLEM.
 * BUT in the next line using the same variable I use a substr to limit the term
   to 3 characters for the hash tag, BUT the result is the first three characters
   of an anchor. I tested this without the substr and indeed the variable contained
   an anchor.
 * I don’t understand why there is this anomaly.
 * I tested the term-date taxonomy to see if it works properly and it does.
