title: What's better of require(dirname(__FILE__).'/'.'myParent.php') than just require('myParent.php')?
body: <p>Lots of famous PHP scripts including WordPress use <code>dirname(__FILE__).'/myParent.php'</code> instead of just <code>'myParent.php'</code> when including files in the same directory of the currently running script.</p>
  
  <p>Aren't they the same thing? Why do you prefer typing more?</p>
  
  <p>Thanks.</p>
