title: PHP Conditional -- Only Display if a String Has Any Value?
body: <p>I need to display the results of either one or two strings.  Each string contains a comma-separated list of items.  I need to concatenate them into a single list.</p>
  
  <p>I know how to do the concatenation.</p>
  
  <p>The issue I have is that sometimes the second string contains entries, sometimes it does not.</p>
  
  <p>If the second string contains data, I want to display the concatenated result (first string and second string).  If the second string is empty, I only want to display the first string.</p>
  
  <p>Can someone help me figure out how to accomplish this?</p>
