PHP读取Excel，批量插入数据库 - PhpSpreadsheet

PhpSpreadsheet   [ˈspredʃiːt]

准备

一、利用composer安装PhpSpreadsheet到项目目录

composer require phpoffice/phpspreadsheet

二、新建public目录，并进入新建test.php

三、在项目根目录新建conn.php，并往里面填写数据库信息

<?php
$servername = "localhost";
$username = "root";
$password = "root";
$dbname = "tt";
 
// 创建连接
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
    die("连接失败: " . $conn->connect_error);
} 
?>

 

 

生成.xlsx文件，并往里面填入信息

test.php里面写

<?php
    require '../vendor/autoload.php';
    
    use PhpOffice\PhpSpreadsheet\Spreadsheet;
    use PhpOffice\PhpSpreadsheet\Writer\Xlsx;
    
    $spreadsheet = new Spreadsheet();
    $sheet = $spreadsheet->getActiveSheet();
    $sheet->setCellValue('A1', 'Welcome to Helloweba.');//将信息填入A1单元格
    
    $writer = new Xlsx($spreadsheet);
    $writer->save('hello.xlsx'); //保存为hello.xlsx

 

 

将Excel的数据批量导入Mysql

require 'vendor/autoload.php';

include('conn.php'); //连接数据库

$reader = \PhpOffice\PhpSpreadsheet\IOFactory::createReader('Xlsx');
$reader->setReadDataOnly(TRUE);
$spreadsheet = $reader->load('students.xlsx'); //载入excel表格

$worksheet = $spreadsheet->getActiveSheet();
$highestRow = $worksheet->getHighestRow(); // 总行数
$highestColumn = $worksheet->getHighestColumn(); // 总列数
$highestColumnIndex = \PhpOffice\PhpSpreadsheet\Cell\Coordinate::columnIndexFromString($highestColumn); // e.g. 5

$lines = $highestRow - 2; 
if ($lines <= 0) {
    exit('Excel表格中没有数据');
}

$sql = "INSERT INTO `t_student` (`name`, `chinese`, `maths`, `english`) VALUES ";

for ($row = 3; $row <= $highestRow; ++$row) {
    $name = $worksheet->getCellByColumnAndRow(1, $row)->getValue(); //姓名
    $chinese = $worksheet->getCellByColumnAndRow(2, $row)->getValue(); //语文
    $maths = $worksheet->getCellByColumnAndRow(3, $row)->getValue(); //数学
    $english = $worksheet->getCellByColumnAndRow(4, $row)->getValue(); //外语

    $sql .= "('$name','$chinese','$maths','$english'),";
}
$sql = rtrim($sql, ","); //去掉最后一个,号
try {
    $db->query($sql);
    echo 'OK';
} catch (Exception $e) {
    echo $e->getMessage();
}

 

 

Mysql批量导出数据到Excel

一、设置表头

require 'vendor/autoload.php';

use PhpOffice\PhpSpreadsheet\Spreadsheet;
use PhpOffice\PhpSpreadsheet\Writer\Xlsx;

include('conn.php'); //连接数据库

$spreadsheet = new Spreadsheet();
$worksheet = $spreadsheet->getActiveSheet();
//设置工作表标题名称
$worksheet->setTitle('学生成绩表');

//表头
//设置单元格内容
$worksheet->setCellValueByColumnAndRow(1, 1, '学生成绩表');
$worksheet->setCellValueByColumnAndRow(1, 2, '姓名');
$worksheet->setCellValueByColumnAndRow(2, 2, '语文');
$worksheet->setCellValueByColumnAndRow(3, 2, '数学');
$worksheet->setCellValueByColumnAndRow(4, 2, '外语');
$worksheet->setCellValueByColumnAndRow(5, 2, '总分');

//合并单元格
$worksheet->mergeCells('A1:E1');

$styleArray = [
    'font' => [
        'bold' => true
    ],
    'alignment' => [
        'horizontal' => \PhpOffice\PhpSpreadsheet\Style\Alignment::HORIZONTAL_CENTER,
    ],
];
//设置单元格样式
$worksheet->getStyle('A1')->applyFromArray($styleArray)->getFont()->setSize(28);

$worksheet->getStyle('A2:E2')->applyFromArray($styleArray)->getFont()->setSize(14);

 

 

二、读取数据

$sql = "SELECT id,name,chinese,maths,english FROM `t_student`";
$stmt = $db->query($sql);
$rows = $stmt->fetchAll(PDO::FETCH_ASSOC);
$len = count($rows);
$j = 0;
for ($i=0; $i < $len; $i++) { 
    $j = $i + 3; //从表格第3行开始
    $worksheet->setCellValueByColumnAndRow(1, $j, $rows[$i]['name']);
    $worksheet->setCellValueByColumnAndRow(2, $j, $rows[$i]['chinese']);
    $worksheet->setCellValueByColumnAndRow(3, $j, $rows[$i]['maths']);
    $worksheet->setCellValueByColumnAndRow(4, $j, $rows[$i]['english']);
    $worksheet->setCellValueByColumnAndRow(5, $j, $rows[$i]['chinese'] + $rows[$i]['maths'] + $rows[$i]['english']);
}

$styleArrayBody = [
    'borders' => [
        'allBorders' => [
            'borderStyle' => \PhpOffice\PhpSpreadsheet\Style\Border::BORDER_THIN,
            'color' => ['argb' => '666666'],
        ],
    ],
    'alignment' => [
        'horizontal' => \PhpOffice\PhpSpreadsheet\Style\Alignment::HORIZONTAL_CENTER,
    ],
];
$total_rows = $len + 2;
//添加所有边框/居中
$worksheet->getStyle('A1:E'.$total_rows)->applyFromArray($styleArrayBody);

 

 

三、下载保存为 .xlsx 文件

$filename = '成绩表.xlsx';
header('Content-Type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet');
header('Content-Disposition: attachment;filename="'.$filename.'"');
header('Cache-Control: max-age=0');

$writer = \PhpOffice\PhpSpreadsheet\IOFactory::createWriter($spreadsheet, 'Xlsx');
$writer->save('php://output');

 

 

四、下载保存为 .xls 文件

$filename = '成绩表.xlsx';
header('Content-Type: application/vnd.ms-excel');
header('Content-Disposition: attachment;filename="'.$filename.'"');
header('Cache-Control: max-age=0');

$writer = \PhpOffice\PhpSpreadsheet\IOFactory::createWriter($spreadsheet, 'xls');
$writer->save('php://output');
