PHP中直接使用sql语句

SELECT * FROM `tf_user` WHERE (`company_id` = '117' OR `other_company_ids` LIKE '%117,%' OR `other_company_ids` LIKE '%,117,%' OR `other_company_ids` LIKE '%,117%') AND `id` != '37' AND `status` = '2' AND `role` = '2';

标准写法，关键字大写。

表名，字段名加`。

值加'。

PHP代码如下：

$sql = "SELECT * FROM `tf_user` WHERE (`company_id` = '".$user_info['company_id']."' OR `other_company_ids` LIKE '%".$user_info['company_id'].",%' OR `other_company_ids` LIKE '%,".$user_info['company_id'].",%' OR `other_company_ids` LIKE '%,".$user_info['company_id']."%') AND `id` != '".$this->user_info['id']."' AND `status` = '2' AND `role` = '2'";
$user_list = $user->query($sql);

原生sql的好处就是能够更加灵活的查询数据！也锻炼sql的能力！

但是一定要写的细心，不然不容易后期维护。
