title: How to use selected WP function in custom PHP file?
body: <p>I have a custom PHP file on which I want to use some WordPress functions such as <em>wp_get_current_user()</em>. I've tried requiring <em>wp-load.php</em>, but that increases the load time significantly as it loads all WP functions.</p>
  
  <p>Is there anyway I can use only the functions I need from WP?</p>
  
  <p>Thanks, Emir</p>
