remove svn files folder using php

some time we forget to export a project on svn and upload that on main server. Result , our main server now have svn file and folders folders. if we want to delete them we have to delete them one by one (if your svn version is old) or we have to upload a new copy of project by exporting project using SVN. It may take a quit long time. So here is the alternate. By using this code you can delete all svn files and folders at once.

1. $path = $_SERVER['DOCUMENT_ROOT'].'/work/remove-svn-php/'; // path of your directory
2. header( 'Content-type: text/plain' ); // plain text for easy display
3. 
   
4. // preconditon: $dir ends with a forward slash (/) and is a valid directory
5. // postcondition: $dir and all it's sub-directories are recursively
6. // searched through for .svn directories. If a .svn directory is found,
7. // it is deleted to remove any security holes.
8. function removeSVN( $dir ) {
9. //echo "Searching: $dirnt";
10. 
    
11. $flag = false; // haven't found svn directory
12. $svn = $dir . '.svn';
13. 
    
14. if( is_dir( $svn ) ) {
15. if( !chmod( $svn, 0777 ) )
16. echo "File permissions could not be changed (this may or may not be a problem--check the statement below).nt"; // if the permissions were already 777, this is not a problem
17. 
    
18. delTree( $svn ); // remove the .svn directory with a helper function
19. 
    
20. if( is_dir( $svn ) ) // deleting failed
21. echo "Failed to delete $svn due to file permissions.";
22. else
23. echo "Successfully deleted $svn from the file system.";
24. 
    
25. $flag = true; // found directory
26. }
27. 
    
28. if( !$flag ) // no .svn directory
29. echo 'No .svn directory found.';
30. echo "nn";
31. 
    
32. $handle = opendir( $dir );
33. while( false !== ( $file = readdir( $handle ) ) ) {
34. if( $file == '.' || $file == '..' ) // don't get lost by recursively going through the current or top directory
35. continue;
36. 
    
37. if( is_dir( $dir . $file ) )
38. removeSVN( $dir . $file . '/' ); // apply the SVN removal for sub directories
39. }
40. }
41. 
    
42. // precondition: $dir is a valid directory
43. // postcondition: $dir and all it's contents are removed
44. // simple function found at http://www.php.net/manual/en/function.rmdir.php#93836
45. function delTree( $dir ) {
46. $files = glob( $dir . '*', GLOB_MARK ); // find all files in the directory
47. 
    
48. foreach( $files as $file ) {
49. if( substr( $file, -1 ) == '/')
50. delTree( $file ); // recursively apply this to sub directories
51. else
52. unlink( $file );
53. }
54. 
    
55. if ( is_dir( $dir ) ){
56. //echo $dir;
57. // die;
58. rmdir( $dir ); // remove the directory itself (rmdir only removes a directory once it is empty)
59. 
    
60. }
61. }
62. 
    
63. // remove all .svn directories in the
64. // current directory and sub directories
65. // (recursively applied)
66. removeSVN($path);
