PHP imports and exports Excel code, php imports and exports excel

1. Import

Importing requires the use of components that can read Excel. There are also better components on the Internet. Here I share the ones I use: Download Extraction code: vxyn. (Note that the two files are referenced)

<&#63;php
//传入要导入的Excel的文件名
function import_to_DB($filename) {
  require_once'reader.php';
  $data = new Spreadsheet_Excel_Reader();   //创建读取Excel的对象
  $data->setOutputEncoding('utf-8');  //设置读取Excel内容后输出的字符编码
  $data->read("data/Excel/{$filename}.xls");
  $db = mysql_connect('localhost', '用户名', '密码') or die("Could not connect to database."); //连接数据库  
  mysql_query("set names 'uft8'"); //输出中文  
  mysql_select_db('数据库名'); //选择数据库  
  error_reporting(E_ALL ^ E_NOTICE);
  for ($i = 1; $i <= $data->sheets[0]['numRows']; $i++) {
    echo $data->sheets[0]['cells'][$i][列数];
    //这里可以把每一行相应列的值插到数据库中，如：
    /*
    $sql="insert "表名" values(对应项...)";
    mysql_query($sql);
    可加上错误判断
    */ 
  } 
&#63;>    

In short, if you can read the value of the corresponding column $data->sheets[0][row][column] in each row of the table, the insertion operation will be easy.

2. Export

Export can use the MIME protocol to easily export table files without relying on any components. Set the header in the following format to export to Excel, and the browser will download it at the same time

header('Content-type: text/html; charset=utf-8');
header("Content-type:application/vnd.ms-excel;charset=UTF-8"); //application/vnd.ms-excel指定输出Excel格式
header("Content-Disposition:filename=表格文件名.xls"); //输出的表格名称

The complete code is as follows:

<&#63;php 
header('Content-type: text/html; charset=utf-8');
header("Content-type:application/vnd.ms-excel;charset=UTF-8"); 
header("Content-Disposition:filename=表格文件名.xls");
$conn = mysql_connect("localhost","root","数据库密码") or die("不能连接数据库");
mysql_select_db("数据库名", $conn);
mysql_query("set names 'UTF-8'");
$sql="select * from 表名 where 条件";

$result=mysql_query($sql);
echo "表头1\t表头2\t表头3\n";
while($row=mysql_fetch_array($result)){
  echo $row[0]."\t".$row[1]."\t".$row[2]."\n";
}
&#63;>

Here, t is actually a format change, and n is a line break. Set the link to this php file in a web page, and when clicked, the browser will automatically save the passed stream as an Excel file.

PHPExcel is a PHP class library used to operate Office Excel documents. It is based on Microsoft's OpenXML standard and PHP language. You can use it to read and write spreadsheets in different formats

Export class

The PHPExcel class exports excel. At the same time, PHPExcel has been streamlined, which can basically meet the function of data export to excel

The code is as follows:

<&#63;php
//载入PHPExcel类
require './phpexcel/PHPExcel.php';
//创建一个excel对象实例
$objPHPExcel = new PHPExcel();
//设置文档基本属性
$objProps = $objPHPExcel->getProperties();
$objProps->setCreator("Lao Mao");
$objProps->setLastModifiedBy("Lao Mao");
$objProps->setTitle("Office XLS Test Document");
$objProps->setSubject("Office XLS Test Document, Demo");
$objProps->setDescription("Test document, generated by PHPExcel.");
$objProps->setKeywords("office excel PHPExcel");
$objProps->setCategory("Test");
//设置当前的sheet索引，用于后续的内容操作。
//一般只有在使用多个sheet的时候才需要显示调用。
//缺省情况下，PHPExcel会自动创建第一个sheet被设置SheetIndex=0
$objPHPExcel->setActiveSheetIndex(0);
//设置当前活动sheet的名称
$objActSheet = $objPHPExcel->getActiveSheet();
$objActSheet->setTitle('测试Sheet');
//设置单元格内容www.jb51.net
//这里的数据可以从数据库中读取，然后再做循环处理
$objPHPExcel->getActiveSheet()->SetCellValue('A1', 'a1');
$objPHPExcel->getActiveSheet()->SetCellValue('A2', 'a2');
$objPHPExcel->getActiveSheet()->SetCellValue('A3', 'a3');
$objPHPExcel->getActiveSheet()->SetCellValue('A4', 'a4');
$objPHPExcel->getActiveSheet()->SetCellValue('A5', 'a5');
$objPHPExcel->getActiveSheet()->SetCellValue('B1', 'b1');
$objPHPExcel->getActiveSheet()->SetCellValue('B2', 'b2');
$objPHPExcel->getActiveSheet()->SetCellValue('B3', 'b3');
$objPHPExcel->getActiveSheet()->SetCellValue('B4', 'b4');
$objPHPExcel->getActiveSheet()->SetCellValue('B5', 'b5');
$objPHPExcel->getActiveSheet()->SetCellValue('C1', 'c1');
$objPHPExcel->getActiveSheet()->SetCellValue('C2', 'c2');
$objPHPExcel->getActiveSheet()->SetCellValue('C3', 'c3');
$objPHPExcel->getActiveSheet()->SetCellValue('C4', 'c4');
$objPHPExcel->getActiveSheet()->SetCellValue('C5', 'c5');
//输出文档
$objWriter = new PHPExcel_Writer_Excel5($objPHPExcel);
//设置header头部信息，并输出到浏览器
//header('Content-Type: application/vnd.ms-excel');
//header("Content-Disposition:attachment; filename=demo.xls");
//header('Cache-Control: max-age=0');
//$objWriter->save('php://output');
//保存至某一位置
$objWriter->save(dirname(__FILE__) . '/demo.xls');

How to import excel:

Code:

<&#63;php
//载入PHPExcel类
include(dirname(__FILE__).'/phpexcel/PHPExcel.php');
$Obj = new PHPExcel_Reader_Excel5();
$Obj->setReadDataOnly(true);
//读取demo.xls文件
$phpExcel = $Obj->load(dirname(__FILE__).'/output.xls');
//获取当前活动sheet
$objWorksheet = $phpExcel->getActiveSheet();
//获取行数
$highestRow = $objWorksheet->getHighestRow();
//获取列数
$highestColumn = $objWorksheet->getHighestColumn();
$highestColumnIndex = PHPExcel_Cell::columnIndexFromString($highestColumn);
//循环输出数据 www.jb51.net
$data = array();
for($row = 1; $row <= $highestRow; ++$row) {
 for($col = 0; $col < $highestColumnIndex; ++$col) {
 $val = $objWorksheet->getCellByColumnAndRow($col, $row)->getValue();
 $data[$row][$col] = trim($val);
 }
}
echo '<pre class="brush:php;toolbar:false">';
print_r($data);
echo '

';

But this method has flaws. The old version of excel has a data upper limit of 65536 rows of data at most. At this time, we cannot export big data through excel, but I guess not many people have such data. , of course, if possible, you can consider using csv to operate
