title: PHP If / Else Statements Without Brackets
body: <p>Is the following always acceptable code? It seems to work, but does it consistently work with all versions of PHP?</p>
  
  <pre><code>if ($x &gt; $y)
      echo 'x is greater';
  elseif ($x == $y)
      echo 'equal';
  else
      echo 'y is greater';
  </code></pre>
  
  <p>Thanks.</p>
