Is it possible to copy an entire folder using the "copy" function in PHP, or is individual copying necessary?

It is not possible to copy an entire folder using the "copy" function in PHP. To copy an entire folder, you would need to recursively copy each file and subfolder within the folder. This can be achieved by using a combination of PHP functions such as opendir, readdir, is_dir, is_file, mkdir, and copy. 

function copyFolder($source, $destination){
    // Open the source directory
    $dir = opendir($source);
    
    // Make the destination directory if it does not exist
    if (!is_dir($destination)) {
        mkdir($destination);
    }
    
    // Loop through the files in the source directory
    while (($file = readdir($dir)) !== false) {
        if ($file != '.' && $file != '..') {
            if (is_dir($source . '/' . $file)) {
                // Recursively copy subfolders
                copyFolder($source . '/' . $file, $destination . '/' . $file);
            } else {
                // Copy files
                copy($source . '/' . $file, $destination . '/' . $file);
            }
        }
    }
    
    // Close the source directory
    closedir($dir);
}

// Usage
copyFolder('source_folder', 'destination_folder');
