  1. /**
  2. * Automatically load related class library files
  3. */
  4. function __autoload($classname){
  5. if(substr($classname,-6)=="Action"){
  6. include APP_PATH.'controllers /'.$classname.'.class.php';
  7. }elseif(substr($classname, -5)=="Model"){
  8. include APP_PATH.'models/'.$classname.'.class.php' ;
  9. }elseif($classname=="Smarty"){
  10. include SYSTEM_PATH.'smarty/Smarty.class.php';
  11. }else{
  12. include APP_PATH.'common/'.$classname.'.class.php' ;
  13. }
  14. }
  15. ?>
Copy code

Another way to include the path:

  1. function __autoload($class_name) {
  2. $path = str_replace('_', DIRECTORY_SEPARATOR, $class_name);
  3. require_once $path.'.php';
  4. }
  5. ?>
Copy code

Instructions: Convert the underscore to the directory separator (DIRECTORY_SEPARATOR). This can effectively manage library files and solve cross-platform problems.
