Are there any specific functions in PHP that can help with copying and renaming files?

To copy and rename files in PHP, you can use the `copy()` function to make a duplicate of the file and then use the `rename()` function to rename the copied file. First, copy the file using `copy($source, $destination)`, where `$source` is the original file path and `$destination` is the path where the copy will be created. Then, use `rename($oldname, $newname)` to rename the copied file.

$source = 'path/to/original/file.txt';
$destination = 'path/to/copied/file.txt';

// Copy the file
if (copy($source, $destination)) {
    // Rename the copied file
    $newname = 'path/to/copied/renamed_file.txt';
    rename($destination, $newname);
    echo "File copied and renamed successfully.";
} else {
    echo "Failed to copy file.";
}
