``,,这段代码加载了数据库模型,并查询 id 为 1 的记录。php,$db = pc_base::load_model('database');,$result = $db>get_one(array('conditions' => 'id=1'));,
``,,这段代码加载了数据库模型,并查询 id 为 1 的记录。php,$db = new PDO('mysql:host=localhost;dbname=your_db', 'username', 'password');,$sql = "SELECT a.*, b.* FROM table1 a JOIN table2 b ON a.id = b.a_id LIMIT :offset, :limit";,$stmt = $db>prepare($sql);,$offset = ($page 1) * $perPage;,$stmt>bindValue(':offset', $offset, PDO::PARAM_INT);,$stmt>bindValue(':limit', $perPage, PDO::PARAM_INT);,$stmt>execute();,$results = $stmt>fetchAll(PDO::FETCH_ASSOC);,
``,,这段代码展示了如何在 PHPCMS 中使用 PDO 进行联合查询并实现分页功能。php,$sql = "SELECT a.*, b.* FROM table1 AS a JOIN table2 AS b ON a.id = b.a_id WHERE a.status = 1";,$result = $db>query($sql);,while ($row = $result>fetch_assoc()) {, // 处理查询结果,},
``,,这段代码展示了如何在 PHPCMS 中执行一个简单的连表查询,并遍历结果集。php,$sql = "SELECT * FROM my_table";,$result = $db>query($sql);,while ($row = $result>fetch_assoc()) {, echo $row['column_name'];,},
``db_select()
,用于从数据库中检索信息。php,$sql = "SELECT * FROM my_table";,$result = $db>query($sql);,while ($row = $result>fetch_assoc()) {, echo $row['column_name'];,},
