Question

thinkphp中的操作mysql的模糊匹配问题

ThinkPHP3.1.3
当我使用以下代码时能正常返回内容
$device = $device_model->where("physical_id like '$physical_id%'")->find();
下面的代码总是返回NULL，
$device = $device_model->where(array('physical_id' => array('like' => "$physical_id%")))->find();
谁能解释一下为什么

Answer 1

$device = $device_model->where(array('physical_id' => array('like',"$physical_id%")))->find();
