chuyển file trong php

The trick is to use the rename() function. If you just wanted to rename a file, you would use the code:

<?php
rename("oldname.txt", "newname.txt");
?>

To move a file, it is something similar:

<?php
// Move file into folder called 'store'
rename("file.txt", "./store/file.txt");
?>
<?php
rename("D:/desktop/12.rar","D:/desktop/a/12.rar");
?>
