Wrote a class to traverse the directory, bulk replace the contents of the solution of the idea

Write a class that traverses directories and replaces file contents in bulk
Write this class before you need it.
Function:
1 traversing all files in the directory (you can specify the suffix name)
2 Bulk Replace file contents (regular, String)
3 Batch replacement file suffix name
4 Batch Replacement file encoding

Use Example:

PHP Code

  
   $dirExplorer = new Direxplorerclass (); $dirExplorer->getdirexplorer (' d:/test1/test2/');                                  Traverse directory d:/test1/test2/$dirExplorer->modifyfileby_replace (' AA ', ' QQ ', ' shift-jis ', ' UTF-8 ', ' txt ', ' txt ');    Replace the AA in all file contents with QQ, convert the file encoding from Shift-jis to UTF-8, and change all txt suffix names to txt

Class Code:

PHP Code
