原生php实现的网页导出和导入excel文件实例,包括上传也是用的原生。还可在exportexcel方法里设置字体等表格样式。

原生PHP网页导出和导入excel文件实例

导出和导入表单代码:

 1 <p style="margin:10px 0"><a href="export.php" class="btn">导出</a></p> 
 2 <form action="import.php" method="post" enctype="multipart/form-data"> 
 3     <div class="control-group"> 
 4         <label>excel表格:</label> 
 5         <input type="file"  name="file"/> 
 6     </div> 
 7     <div class="control-group"> 
 8         <input type="submit"  value="导入" /> 
 9     </div> 
10 </form>


excel导出:

 1 $query = mysql_query("select * from user limit 50");  
 2 $i =0; 
 3 $list = array(); 
 4 while($row=mysql_fetch_array($query)){  
 5     $list[$i]['id'] = $row['id'];  
 6     $list[$i]['username'] = $row['username'];  
 7     $list[$i]['password'] = $row['password'];  
 8     $i++; 
 9 }  
10  
11 $title = array('id', '邮箱', '密码'); //设置要导出excel的表头 
12 exportexcel($list, '素材火用户表', $title);


exportexcel方法代码:

 1 function exportexcel($data, $savefile = null, $title = null, $sheetname = 'sheet1') { 
 2     require_once 'phpexcel.class.php'; 
 3     //若没有指定文件名则为当前时间戳 
 4     if (is_null($savefile)) { 
 5         $savefile = time(); 
 6     } 
 7     //若指字了excel表头,则把表单追加到正文内容前面去 
 8     if (is_array($title)) { 
 9         array_unshift($data, $title); 
10     } 
11     $objphpexcel = new phpexcel(); 
12     //excel内容 
13     $head_num = count($data); 
14  
15     foreach ($data as $k => $v) { 
16         $obj = $objphpexcel->setactivesheetindex(0); 
17         $row = $k + 1; //行 
18         $nn = 0; 
19  
20         foreach ($v as $vv) { 
21             $col = chr(65 + $nn); //列 
22             $obj->setcellvalue($col . $row, $vv); //列,行,值 
23             $nn++; 
24         } 
25     } 
26     //设置列头标题 
27     for ($i = 0; $i < $head_num - 1; $i++) { 
28         $alpha = chr(65 + $i); 
29         $objphpexcel->getactivesheet()->getcolumndimension($alpha)->setautosize(true); //单元宽度自适应  
30         $objphpexcel->getactivesheet()->getstyle($alpha . '1')->getfont()->setname("candara");  //设置字体 
31         $objphpexcel->getactivesheet()->getstyle($alpha . '1')->getfont()->setsize(12);  //设置大小 
32         $objphpexcel->getactivesheet()->getstyle($alpha . '1')->getfont()->getcolor()->setargb(phpexcel_style_color::color_black); //设置颜色 
33         $objphpexcel->getactivesheet()->getstyle($alpha . '1')->getalignment()->sethorizontal(phpexcel_style_alignment::horizontal_center); //水平居中 
34         $objphpexcel->getactivesheet()->getstyle($alpha . '1')->getalignment()->setvertical(phpexcel_style_alignment::vertical_center); //垂直居中 
35         $objphpexcel->getactivesheet()->getstyle($alpha . '1')->getfont()->setbold(true); //加粗 
36     } 
37  
38     $objphpexcel->getactivesheet()->settitle($sheetname); //题目 
39     $objphpexcel->setactivesheetindex(0); //设置当前的sheet   
40     header('content-type: application/vnd.ms-excel'); 
41     header('content-disposition: attachment;filename="' . $savefile . '.xls"');//文件名称 
42     header('cache-control: max-age=0'); 
43     $objwriter = phpexcel_iofactory::createwriter($objphpexcel, 'excel5'); //excel5 
44     $objwriter->save('php://output'); 
45 }


excel导入:

 1 $tmp = $_files['file']['tmp_name']; 
 2 if (empty($tmp)) { 
 3     echo '请选择要导入的excel文件!'; 
 4     exit; 
 5 } 
 6  
 7 $save_path = "uploads/"; 
 8 $filename = $save_path . date('ymdhis') . ".xls"; //上传后的文件保存路径和名称  
 9 if (copy($tmp, $filename)) { 
10     require_once 'phpexcel.class.php'; 
11     require_once 'phpexcel/reader/excel5.php'; 
12  
13  
14     $phpreader = new phpexcel_reader_excel5(); //phpexcel_reader_excel2007 phpexcel_reader_excel5 
15     //载入文件 
16     $phpexcel = $phpreader->load($filename); 
17  
18     //获取表中的第一个工作表,如果要获取第二个,把0改为1,依次类推 
19     $currentsheet = $phpexcel->getsheet(0); 
20     //获取总列数 
21     $allcolumn = $currentsheet->gethighestcolumn(); 
22     //获取总行数 
23     $allrow = $currentsheet->gethighestrow(); 
24     //循环获取表中的数据,$currentrow表示当前行,从哪行开始读取数据,索引值从0开始 
25     for ($currentrow = 1; $currentrow <= $allrow; $currentrow++) { 
26         //从哪列开始,a表示第一列 
27         for ($currentcolumn = 'a'; $currentcolumn <= $allcolumn; $currentcolumn++) { 
28             //数据坐标 
29             $address = $currentcolumn . $currentrow; 
30             //读取到的数据,保存到数组$arr中 
31             $data[$currentrow][$currentcolumn] = $currentsheet->getcell($address)->getvalue(); 
32         } 
33     } 
34  
35     $add_time = date('y-m-d h:i:s', time()); 
36     foreach ($data as $k => $v) { 
37         if ($k > 1) { 
38             $sql = "insert into user (username,password) values ('" . $v['b'] . "', '" . $v['c'] . "')"; 
39  
40             mysql_query($sql); 
41         } 
42     } 
43  
44     $sql = "select * from user"; 
45     $result = mysql_query($sql); 
46     $tip = '用户导入成功' . ',现在' . mysql_num_rows($result) . '条数据了!'; 
47     echo "<script>alert('" . $tip . "');history.go(-1);</script>";
