title: How to alias a function in PHP?
body: <p>Is it possible to alias a function with a different name in PHP? Suppose we have a function with the name <code>sleep</code>. Is there a way to make an alias called <code>wait</code>?</p>
  
  <p>By now I'm doing like this:</p>
  
  <pre><code>function wait( $seconds ) {
      sleep($seconds);
  }
  </code></pre>
