Answer 1

where conditions:

    $where['warehouse'] = '办公用品仓库';
    $where['name'] = array('in', array('笔记本电脑','万用表','鼠标'));

Answer 2

// 去除 name 值，去重处理
$where['name'] = ['in', implode(',', array_unique(array_column( $data, 'name')))];

Answer 3

thinkphp 3.23?

$where['warehouse'] = '办公用品仓库';
$where['name'] = array('in', array('笔记本电脑','万用表','鼠标'));
//or
$where['warehouse'] = '办公用品仓库';
$where['name'] = array('in', '笔记本电脑,万用表,鼠标');

thinkphp 5.0?

where('warehouse','in','笔记本电脑,万用表,鼠标');
// or
where('warehouse','in',['笔记本电脑','万用表','鼠标']);
