title: Multiple @todo in phpDoc
body: <p>I have multiple todo items I want to add for a function.</p>
  
  <p>What is the correct way to add them in a phpDoc comment block?</p>
  
  <p>I understand that I should use the @todo tag. 
  But I am unsure of whether I should use a single @todo tag per item, or one @todo tag for the whole list.</p>
