title: Long if statements and PSR-2
body: <p>I'm about to migrate some code to the PSR-2 standard. In my code i have if statements with multiple lines as expression: </p>
  
  <pre><code>if (    $field-&gt;getBlockMode() == FieldInterface::BLOCK_MODE_HIDEVAR &amp;&amp;
          !isset($this-&gt;enabledBlocks[$field-&gt;getBlock()])
  ) {
  
  }
  </code></pre>
  
  <p>What's the best practice to write such expressions?</p>
