PHP最简单的模板引擎之一

自用模板引擎。

1. define('APP_PATH', __DIR__);
2. class Template{
3. private static $_vars;
4. private static $_path;
5. private static $_prefix;
6. private function __construct() {}
7. public static function init($path = null) {
8. if(isset($path)&&($path!='')) self::$_path=APP_PATH.'/templates/'.$path.'/';
9. else self::$_path = APP_PATH.'/templates/';
10. self::$_vars = array();
11. }
12. public static function set_path($path) {
13. self::$_path = $path;
14. }
15. public static function set_prefix($prefix) {
16. self::$_prefix = $prefix;
17. }
18. public static function assign($key, $value = null)
19. { if(!isset(self::$_vars)) self::init();
20. if (is_array($key)) self::$_vars = array_merge(self::$_vars,$key);
21. elseif (($key != '')&&(isset($value)))
22. self::$_vars[$key] = $value;
23. }
24. public static function fetch($file) {
26. if(!isset(self::$_vars)) self::init();
27. if(count(self::$_vars)>0)
28. { extract(self::$_vars,EXTR_PREFIX_ALL,self::$_prefix);
29. self::$_vars = array();
30. }
31. ob_start();
32. include self::$_path . $file ;
33. $contents = ob_get_contents();
34. ob_end_clean();
35. self::$_path = null;
36. return preg_replace('!\s+!', ' ', $contents);
37. }
38. }
39. ?>
