本文实例讲述了CodeIgniter分页类pagination使用方法。分享给大家供大家参考,具体如下:
controller控制器(application/controller/page.php文件):
public function index() { $this->load->model ( 'home_model' , '' , TRUE); $config= array(); $config['per_page'] = $this->per_page; //每页显示的数据数 $current_page = intval($this->input->get_post('per_page',true)); //获取当前分页页码数 //page还原 if(0 == $current_page) { $current_page = 1; } $offset = ($current_page - 1 ) * $config['per_page']; //设置偏移量 限定 数据查询 起始位置(从 $offset 条开始) $result = $this->home_model->index($offset,$config['per_page'],$order='id desc'); $config['base_url'] = $this->config->item('base_url').'admin/home/index?'; $config['first_link'] = $this->first_link;//首页 $config['prev_link'] = $this->prev_link;//上一页 $config['next_link'] = $this->next_link;//下一页 $config['last_link'] = $this->last_link;//尾页 $config['total_rows'] = $result['total'];//总条数 $config['num_links'] = 3;//页码连接数 $config['use_page_numbers'] = TRUE; $config['page_query_string'] = TRUE; $this->load->library('pagination');//加载ci pagination类 $this->pagination->initialize($config); $result = array( 'list' => $result['list'], 'total' => $result['total'], 'current_page' => $current_page, 'per_page' => $config['per_page'], 'page' => $this->pagination->create_links(), ); $this->load->view ( 'admin/home' , $result ); }
model模型(application/model/home_model.php文件):
public function index($offset,$num,$order='id desc') { $query = $this->db->query( "SELECT Name_cn,Mall_type,create_time FROM smzdm_mall WHERE Is_deleted = 0 order by {$order} limit {$offset},{$num}"); return array( 'total' => $this->db->count_all('smzdm_mall',array('Is_deleted'=>'0')), 'list' => $query->result(), ); }

Arrays can be stored in PHP sessions. 1. Start the session and use session_start(). 2. Create an array and store it in $_SESSION. 3. Retrieve the array through $_SESSION. 4. Optimize session data to improve performance.

PHP session garbage collection is triggered through a probability mechanism to clean up expired session data. 1) Set the trigger probability and session life cycle in the configuration file; 2) You can use cron tasks to optimize high-load applications; 3) You need to balance the garbage collection frequency and performance to avoid data loss.

Tracking user session activities in PHP is implemented through session management. 1) Use session_start() to start the session. 2) Store and access data through the $_SESSION array. 3) Call session_destroy() to end the session. Session tracking is used for user behavior analysis, security monitoring, and performance optimization.

Using databases to store PHP session data can improve performance and scalability. 1) Configure MySQL to store session data: Set up the session processor in php.ini or PHP code. 2) Implement custom session processor: define open, close, read, write and other functions to interact with the database. 3) Optimization and best practices: Use indexing, caching, data compression and distributed storage to improve performance.

In PHP, iterating through session data can be achieved through the following steps: 1. Start the session using session_start(). 2. Iterate through foreach loop through all key-value pairs in the $_SESSION array. 3. When processing complex data structures, use is_array() or is_object() functions and use print_r() to output detailed information. 4. When optimizing traversal, paging can be used to avoid processing large amounts of data at one time. This will help you manage and use PHP session data more efficiently in your actual project.

The session realizes user authentication through the server-side state management mechanism. 1) Session creation and generation of unique IDs, 2) IDs are passed through cookies, 3) Server stores and accesses session data through IDs, 4) User authentication and status management are realized, improving application security and user experience.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
