 1 | Codeigniter-Excel-Export
 2 | ========================
 3 | 
 4 | An Codeigniter library for exporting the data from database to Excel file. 
 5 | 
 6 | 一个用于导出数据库数据到Excel文件的PHP库，用于Codeigniter框架中。(支持Excel中包含中文文字)
 7 | 
 8 | 使用方法:
 9 | ========================
10 | 
11 | 1. 复制Excel.php到相应目录(application/libraries目录下)
12 | ------------------------
13 | 
14 | 2. 创建数据结果集
15 | ------------------------
16 | 
17 | <?php
18 | public function export() {
19 |     $this->load->library('excel');
20 | 
21 |     $sql = $this->db->get('dbtable');
22 | 
23 |     $this->excel->filename = 'abc123';
24 |     $this->excel->make_from_db($sql);
25 | }
26 | ?>
27 | 
28 | 3. 导出到Excel文
29 | --------------------------
30 | 
31 | <?php
32 | public function export() {
33 |     $titles = array('
34 |         'field1', 'field2', 'field3'
35 |     ');
36 |     $array = array();
37 |     for ($i = 0; $i <= 100; $i++) {
38 |         $array[] = array($i, $i+1, $i+2);
39 |     }
40 |     $this->excel->make_from_array($titles, $array);
41 | }
42 | ?>
