一、因为项目中的一个报表需要合并三个表的数据,所以分表查询再合并数据,利用PHP数组函数进行排序,搜索。三表合并后的数组结构如下:
Array ( [0] => Array ( [history_id] => 12 [sla_group_id] => 1 [sla_id] => -1 [create_time] => 1513057695 [tasklog_id] => 12 [tasklog_time] => 2017-12-12 13:48:15 [tasklog_name] => window_2008 [tasklog_type] => 分组立即调度 [tasklog_user] => admin [tasklog_status] => 3 ) [1] => Array ( [history_id] => 11 [sla_group_id] => 1 [sla_id] => 1 [create_time] => 1513057563 [tasklog_id] => 11 [tasklog_time] => 2017-12-12 13:46:03 [tasklog_name] => centos7_USHARK [tasklog_type] => 一小时备份频率 [tasklog_user] => 系统自动 [tasklog_status] => 3 ) [2] => Array ( [history_id] => 19 [sla_group_id] => 1 [sla_id] => 98 [create_time] => 1513059714 [tasklog_id] => 19 [tasklog_time] => 2017-12-12 14:21:54 [tasklog_name] => huawei_fusion_backup [tasklog_type] => 华为虚拟化备份 [tasklog_user] => ushark.net [tasklog_status] => 2 ) [3] => Array ( [history_id] => 41 [sla_group_id] => 0 [sla_id] => -1 [create_time] => 1513069534 [status] => 2 [tasklog_id] => 41 [tasklog_time] => 2017-12-12 17:05:34 [tasklog_name] => centos7-11自增非整数测试 [tasklog_user] => admin [tasklog_type] => 立即调度 [tasklog_status] => 2 ) [4] => Array ( [history_id] => 40 [sla_group_id] => 0 [sla_id] => -1 [create_time] => 1513067574 [status] => 2 [tasklog_id] => 40 [tasklog_time] => 2017-12-12 16:32:54 [tasklog_name] => win2008安装MySQL [tasklog_user] => impp.cc [tasklog_type] => 策略备份 [tasklog_status] => 2 ) [5] => Array ( [history_id] => 39 [sla_group_id] => 0 [sla_id] => -1 [create_time] => 1513067399 [status] => 2 [tasklog_id] => 39 [tasklog_time] => 2017-12-12 16:29:59 [tasklog_name] => Linux下文件 [tasklog_user] => ppstorm.com [tasklog_type] => 立即调度 [tasklog_status] => 2 ) )
二、二维数组排序、搜索
// HTTP GET values $length = (int) $this->input->get(‘length‘, true); $start = (int) $this->input->get(‘start‘, true); $order = trim($this->input->get(‘order‘, true)); $sort = trim($this->input->get(‘dir‘, true)); $search = trim($this->input->get(‘search‘, true)); // 三表数据 $vm_group = $this->safe->vm_group_task(); $vm_tasklog = $this->safe->vm_tasklog(); $vm_mounts_log = $this->safe->vm_mounts_log(); // 合并数据 $tasklog = array_merge($vm_group, $vm_tasklog, $vm_mounts_log); // !!! 二维数据搜索 !!! if (!empty($search)) { foreach ($tasklog as $sk => $sv) { if (mb_stripos($sv[‘tasklog_name‘], $search) === false && mb_stripos($sv[‘tasklog_type‘], $search) === false && mb_stripos($sv[‘tasklog_user‘], $search) === false ) { unset($tasklog[$sk]); continue; } } } // 总记录 $total_record = count($tasklog); // 排序 switch ($order) { case 1: $sort_key = ‘tasklog_name‘; break; case 2: $sort_key = ‘tasklog_type‘; break; case 3: $sort_key = ‘tasklog_user‘; break; case 4: $sort_key = ‘tasklog_time‘; break; case 5: $sort_key = ‘tasklog_status‘; break; default: $sort_key = ‘tasklog_id‘; break; } $sort_arr = array_column($tasklog, $sort_key); $desc_asc = $sort === ‘desc‘ ? SORT_DESC : SORT_ASC; array_multisort($sort_arr, $desc_asc, $tasklog); // !!! 二维数据排序 !!! // 取指定长度 $output_arr = array_slice($tasklog, $start, $length);
