Before moving the file, we use copy to move the file in the object... php. let's take a look at a simple example. he has moved the directory and the directory file. I hope this article will help you.

Method 1: copy + unlink

My idea is: move = new + delete. Create a folder in the target directory before moving the folder, copy the file and directory, and delete the folder.

 . [1] => .. [2] => a [3] => B [4] => c [5] => dir [6] => dir. php [7] => dir2 [8] => dir2.php [9] => function_file.php [10] => homework. php) you can see that the scandir function outputs two redundant values: [0] =>. [1] => .. this is useful to us. write an if statement to kill them. */Foreach ($ files as $ file) {// traverses the $ files array for copying and deleting folders and files in the array. if (in_array ($ file, array ('. ','.. ') {// array ('. ','.. ') a new one is only. and .. and find the $ file. and .. these two values are continue;} $ subFrom = $ from. '/'. $ file; // Convert the folder or file name after traversal into a new path $ subTo = $. '/'. $ file; if (is_dir ($ subFrom) {@ mkdir ($ subTo); // checks whether $ subFrom is a directory. if it is a directory, it is under the Target Directory, create a directory moveDir ($ subFrom, $ subTo); // recursively execute the new directory.} Else {// if it is not a directory, copy the file directly. after copying, delete the file. copy ($ subFrom, $ subTo); unlink ($ subFrom); // delete all files} @ rmdir ($ subFrom ); // delete all directories} return true;}?> MoveDir ('C:/Users/Administrator/Desktop/100', 'E: '); // The address of the file or directory to be moved.

Method 2: rename

1. for files, rename can be moved between different drive letters.

2. for empty folders, rename can be moved between different drive letters, but the parent directory of the target folder must exist.

3. for non-empty folders, they can only be moved under the same drive letter. However, 1 and 3 should be able to deal with almost all applications.

For a 40 m file, the copy + unlink method takes 7.6249899864197 seconds, while the rename method only requires 0.024738788604736, 300 times faster.
