php - 从 mysql 数组中回显特定值

Question

所以我尝试使用 php (wordpress) 从 mysql 表中回显值

大多数领域都表现良好

但是当我尝试回显

$row->form 我得到一个像这样返回的数组:

string(832) "[{"id":"1","is_email":"false","add_to_day_hour_info":"false","add_to_day_hour_body":"false","translation":"First name","value":"firstname1"},{"id":"2","is_email":"false","add_to_day_hour_info":"false","add_to_day_hour_body":"false","translation":"Last name","value":"lastname1"},{"id":"6","is_email":"false","add_to_day_hour_info":"false","add_to_day_hour_body":"false","translation":"Accomodation","value":"Hotel Sample"},{"id":"3","is_email":"true","add_to_day_hour_info":"false","add_to_day_hour_body":"false","translation":"Email","value":"sample@example.com"},{"id":"4","is_email":"false","add_to_day_hour_info":"false","add_to_day_hour_body":"false","translation":"Phone","value":"333333"},{"id":"5","is_email":"false","add_to_day_hour_info":"false","add_to_day_hour_body":"false","translation":"Message","value":"Goog Job"}]" 

string(973) "[{"id":"1","is_email":"false","add_to_day_hour_info":"false","add_to_day_hour_body":"false","translation":"First name","value":"ddd"},{"id":"2","is_email":"false","add_to_day_hour_info":"false","add_to_day_hour_body":"false","translation":"Last name","value":"ddd"},{"id":"3","is_email":"true","add_to_day_hour_info":"false","add_to_day_hour_body":"false","translation":"Email","value":"sample1@example.com"},{"id":"6","is_email":"false","add_to_day_hour_info":"false","add_to_day_hour_body":"false","translation":"Accomodation\/PikUp Address:","value":"House no 203"},{"id":"8","is_email":"false","add_to_day_hour_info":"false","add_to_day_hour_body":"false","translation":"Room Number:","value":"d"},{"id":"4","is_email":"false","add_to_day_hour_info":"false","add_to_day_hour_body":"false","translation":"Phone","value":"44444"},{"id":"5","is_email":"false","add_to_day_hour_info":"false","add_to_day_hour_body":"false","translation":"Message","value":"444444"}]" 

这是我的 sql 代码:

$result = $wpdb->get_results( "SELECT * FROM wp_table_1");

foreach($result as $row)
 {
echo $row->form;
}

我想重复名字。谢谢

Answer 1

echo $row->form;

上面的行将回显数组。

要仅回显名字，请按照以下模式使用

echo $row->form['first_name'];
