  2. /**
  3. * Automatically load related class library files
  4. */
  5. function __autoload($classname){
  6. if(substr($classname,-6)=="Action"){
  7. include APP_PATH.'controllers /'.$classname.'.class.php';
  8. }elseif(substr($classname, -5)=="Model"){
  9. include APP_PATH.'models/'.$classname.'.class.php' ;
  10. }elseif($classname=="Smarty"){
  11. include SYSTEM_PATH.'smarty/Smarty.class.php';
  12. }else{
  13. include APP_PATH.'common/'.$classname.'.class.php' ;
  14. }
  15. }
  16. ?>
Copy code

Another way to include the path:

  2. function __autoload($class_name) {
  3. $path = str_replace('_', DIRECTORY_SEPARATOR, $class_name);
  4. require_once $path.'.php';
  5. }
  6. ?>
Copy code

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