title: PHP - exit from IF block
body: <p>How can I exit a <code>if</code> block if a certain condition is met?</p>
  
  <p>I tried using <code>break</code> but it doesn't work:</p>
  
  <pre><code>if($bla): 
    $bla = get_bla();
    if(empty($bla)) break;
    do($bla);
  endif;
  </code></pre>
  
  <p>it says: Fatal error: Cannot break/continue 1 level in...</p>
