Thinkphp clears cache

Dedecms has the cache clearing function, so I tried to study it. The result shows that I am in the fog. hi .... as a result, I checked it online and wrote a Cache clearing function based on my website.

Tp execution code:

1. // Obtain the absolute path of the desired directory and Directory
2. Public function cache (){
3. /// The front-end submits the request in ajax get mode. here we will first judge
4. If ($ _ POST ['type']) {
5. // Obtain the passed value
6. $ Type = $ _ POST ['type'];
7. // Cut the passed value. I have "-" cut
8. $ Name = explode ('-', $ type );
9. // Obtain the number of slices to facilitate the following cycle
10. $ Count = count ($ name );
11. // Call the above method cyclically
12. For ($ I = 0; $ I <$ count; $ I ++ ){
13. // Obtain the absolute path of the object
14. $ Abs_dir = dirname (_ FILE __))));
15. // Combined path
16. $ Pa = $ abs_dir. '\ index \ Runtime \\';
17. $ Runtime = $ abs_dir. '\ index \ Runtime \~ Runtime. php ';
18. If (file_exists ($ runtime) // checks whether the object exists.
19. {
20. Unlink ($ runtime); // delete a file
21. }
22. // Call the method to delete all objects in a folder
23. $ This-> rmFile ($ pa, $ name [$ I]);
24. }
25. // Provides prompt information
26. $ This-> ajaxReturn (1, 'cleared successfully', 1 );
27. } Else {
28. $ This-> display ();
29. }
30. }
31. Public function rmFile ($ path, $ fileName) {// delete the execution method
32. // Remove spaces
33. $ Path = preg_replace ('/(\/) {2, }|{\\\}{ 1,}/', '/', $ path );
34. // Obtain The Complete Directory
35. $ Path. = $ fileName;
36. // Determine whether the file is a file directory
37. If (is_dir ($ path )){
38. // Open the file
39. If ($ dh = opendir ($ path )){
40. // Retrieve the file directory name
41. While ($ file = readdir ($ dh ))! = False ){
42. // Delete one by one
43. Unlink ($ path. '\'. $ file );
44. }
45. // Close the file
46. Closedir ($ dh );
47. }
48. }
49. }

Tp: front-end code (a little crude)
