PHP file operations (create, copy, move, and delete files and folders) are easy to use. For more information, see. The code is as follows:
/**
* File operations
*
* Example:
* FileUtil: createDir ('a/1/2/3'); create a folder named a/1/2/3
* FileUtil: createFile ('B/1/2/3'); create a 3 file under the B/1/2/folder in the test.
* FileUtil: createFile ('B/1/2/3.exe'); create a 3.exe file under B/1/2/folder.
* FileUtil: copyDir ('B', 'd/e'); create a d/e folder in the copy folder and copy the content in the B folder.
* FileUtil: copyFile ('B/1/2/3.exe', 'B/B/3.exe'); create a B/B folder for the copied file, copy the 3.exe file in the B/1/2 folder.
* FileUtil: moveDir ('a/',' B/C'); test the mobile folder to create a B/c folder and move the content in folder, and delete the folder.
* FileUtil: moveFile ('B/1/2/3.exe', 'B/d/3.exe'); test to create a B/d folder for a mobile file, and move 3.exe in B/1/2
* FileUtil: unlinkFile ('B/d/3.exe'); test deleting a file B/d/3.exe
* FileUtil: unlinkDir ('D'); test the function of deleting a folder and deleting a folder.

The code is as follows:
$ Fu = new FileUtil ();
$ Fu-> copyFile ('a/1/2/3', 'A/1/2/4 ');
