Drupal

As I have started my internship of Ms Degree in Drupal, I was so keen to get into the things and I really want to learn how Drupal is working, Drupal is a amazing content management framework written using PHP as backend language so to be a master in Drupal, I decided to learn core PHP but after reading few books in last 3 months or so ,on core php I didn’t found anything related to MULTITHREADED programming techniques in php it was a real shock for me to get known that php is not supporting multithreaded programming.
