title: Add space in String
body: <p>I would like to add space during string assignment like:</p>
  
  <pre><code>$movie_genre.= $row["movie_genre"]."   ";
  </code></pre>
  
  <p>where it should display genre1 genre2 genre3 and so on. Single space between these three genres is required. Currently it is showing genre1genre2genre3</p>
