title: PHP: Can't display simple addition
body: <p>Basically I'm trying to add 3 numbers together by storing them as variables then adding them up 3+4+5 and it's coming back as 312? No clue why.. code is below:</p>
  
  <pre><code>&lt;?php
      echo"
      &lt;table border='1'&gt;
          &lt;tr&gt;
              &lt;td&gt;
                  ".date('l jS \of F Y h:i:s A')."
              &lt;/td&gt;
              &lt;td&gt;
                   ".
                  $N1 = 3;
                  $N2 = 4;
                  $N3 = 5;
                  $sum_total = $N1 + $N2 + $N3;
  
                  print ("$sum_total") ."
  
              &lt;/td&gt;
          &lt;/tr&gt;
      &lt;/table&gt;";
  ?&gt;
  </code></pre>
