Array
(
[1] => Array
    (
        [id] => 1
        [sort] => 1
    )

[3] => Array
    (
        [id] => 3
        [sort] => 3
    )

[2] => Array
    (
        [id] => 2
        [sort] => 2
    )

)

我如何对它进行排序,以便使用内部"排序"键重新排序？即上面看起来像这样:

Array
(
[1] => Array
    (
        [id] => 1
        [sort] => 1
    )

[2] => Array
    (
        [id] => 2
        [sort] => 2
    )

[3] => Array
    (
        [id] => 3
        [sort] => 3
    )

)

我正在尝试构建自己的简单的wordpress密码更改脚本（嗯，实际上是基于插件）-密码已成功更改-但更改完成后却注销了我！下面是使用的代码。谁能看到我被注销的地方以及如何防止它退出？谢谢！

$update = $wpdb->query($wpdb->prepare("UPDATE {$wpdb->users} SET `user_pass` = %s WHERE `ID` = %d",array(wp_hash_password($_POST['admin_pass1']),$user_ID)));

if(!is_wp_error($update))
{
    wp_cache_delete($user_ID,'users');
    wp_cache_delete($user->user_login,'userlogins');
    wp_logout();
    if (wp_signon(array('user_login'=>$user->user_login,'user_password'=>$_POST['admin_pass1']),false)):
        wp_redirect(admin_url());
    endif;
    ob_start();
}

有人可以帮忙 - 我准备把头发撕掉这个;(

列名称'%Discover%'无效.

SELECT * FROM mdl_course_sections WHERE summary LIKE "%Discover%" AND course = 22

我正在寻找'发现' - 但为什么它将它视为一个列？

谢谢!

好的,我有以下数组:

Array
(
   [0] => Array
    (
        [id] => 6
        [name] => This Course
        [time] => 1288082700
        [description] => blah blah . 
        [link] => http://this.com/?g=5
        [course] => 22
    )

[1] => Array
    (
        [id] => 2
        [name] => Workshop
        [time] => 1287561600
        [description] => This description
        [link] => http://this.com/?g=5
        [session] => 8
        [course] => 23
        [type] => standard
        [adobelink] => 
    )

)

如何使用内部'time'键对整个数组进行排序？

谢谢!
