title: PHP: strftime(), date() or DateTime, Which is better?
body: <p>I am curious to know if there is any advantage in PHP of using <code>strftime()</code> over <code>date()</code> or vice versa. </p>
  
  <p>A class I downloaded used the <code>strftime()</code>. However, since it does not support all time formats on some systems, I want to change it to use <code>date()</code> instead. I was wondering if there are any major differances or advantages in using one over the other.</p>
  
  <p>What about the fact that <code>strftime()</code> only supports date formats that are supported by that servers c library? Does <code>date()</code> have any similar restrictions?</p>
