解析錯誤：語法錯誤，PHP中的意外T_DOUBLE_ARROW

Question

我試圖更新functions.php與此，這是從網站上的附件插件直接複製的代碼，但我得到一個T_DOUBLE_ARROW語法錯誤，任何想法爲什麼？ ： - ？

<?php 

function my_attachments($attachments) 
{ 
    $fields   => array(
    array(
     'name'  => 'title',       // unique field name 
     'type'  => 'text',       // registered field type 
     'label'  => __('Title', 'attachments'), // label to display 
     'default' => 'title',       // default value upon selection 
    ), 
    array(
     'name'  => 'caption',      // unique field name 
     'type'  => 'textarea',      // registered field type 
     'label'  => __('Caption', 'attachments'), // label to display 
     'default' => 'caption',      // default value upon selection 
    ), 
); 

    $args = array(

    // title of the meta box (string) 
    'label'   => 'My Attachments', 

    // all post types to utilize (string|array) 
    'post_type'  => array('post', 'page'), 

    // meta box position (string) (normal, side or advanced) 
    'position'  => 'normal', 

    // meta box priority (string) (high, default, low, core) 
    'priority'  => 'high', 

    // allowed file type(s) (array) (image|video|text|audio|application) 
    'filetype'  => null, // no filetype limit 

    // include a note within the meta box (string) 
    'note'   => 'Attach files here!', 

    // text for 'Attach' button in meta box (string) 
    'button_text' => __('Attach Files', 'attachments'), 

    // text for modal 'Attach' button (string) 
    'modal_text' => __('Attach', 'attachments'), 

    // which tab should be the default in the modal (string) (browse|upload) 
    'router'  => 'browse', 

    // fields array 
    'fields'  => $fields, 

); 

    $attachments->register('my_attachments', $args); // unique instance name 
} 

add_action('attachments_register', 'my_attachments');
