使用JavaScript解码PHP调用? [关闭]

In a .php file I have some PHP code which is encoded with Base64, and it decodes fine with some base64_decode code that is in a .js file.

However in the same .php file using JavaScript, I have been calling the same PHP code. Even though this is still being encoded, it does not appear to be decoded from the same .js file.

<?php
    $items_folder="http://domain/items/";
    $items_folder_enc=base64_encode($items_folder);
?>

<script type='text/javascript'>
var itemsnew=<?php echo json_encode($items_folder_enc); ?>;

What can I change so that the <?php echo json_encode($items_folder_enc); ?>; is decoded like its PHP counterpart?

If you want to decode server-side and send $items_folder to client as plain text then:

var itemsnew = "<?php echo base64_decode($items_folder_enc); ?>";

If you want to decode client-side and send $items_folder to client in an "encoded" manner then:

var itemsnew = atob("<?php echo $items_folder_enc; ?>");

In the later case, you might want to check for atob support and create a base64 decoding user function if browser doesn't support it.
