PHP按键替换数组值

Question

我有一个数组：

 Array
(
    [0] => Array
        (
            [id] => 11
            [email_theme_id] => 1_5
            [email_template] => Array()
            [add_template] => 
            [email_template_subject] => Your free and bargain ebook alert for Sunday
            [last_update] => 1392314609
        )

    [1] => Array
        (
            [id] => 10
            [email_theme_id] => 2_12
            [email_template] => Array()
            [add_template] => 
            [email_template_subject] => Your free and bargain ebook alert for Sunday
            [last_update] => 1392314609
        )

)

我需要更改数组项[1] [email_template]值，那么我该如何用PHP做呢？

Answer 1

试试：

$data[1]['email_template'] = 'new value';

$data是您的数据变量。

Answer 2

尝试

$item[1][email_template] = array('new value');

甚至你可以这样做

$item[1][email_template][0] = 'new value';

考虑到您要更新阵列
