Composer安装
如果你尚未安装Composer,请先安装 Composer。Composer是PHP的依赖管理工具,它可以方便地安装和管理项目中的第三方库。
安装phpoffice/phpspreadsheet: 触发控制器里面的方法 wdjzdc()
在控制中引入
use PhpOfficePhpSpreadsheetSpreadsheet;
use PhpOfficePhpSpreadsheetWriterXlsx;
//wdjzdc数据导出
public function wdjzdc()
{
$spreadsheet = new Spreadsheet();
$worksheet = $spreadsheet->getActiveSheet();
//设置工作表标题名称
$worksheet->setTitle('wdjz客户表');
//表头
//设置单元格内容
$worksheet->setCellValueByColumnAndRow(1, 1, 'wdjz无毒样板客户表');
$worksheet->setCellValueByColumnAndRow(1, 2, 'name');
$worksheet->setCellValueByColumnAndRow(2, 2, 'phone');
$worksheet->setCellValueByColumnAndRow(3, 2, 'radio1');
$worksheet->setCellValueByColumnAndRow(4, 2, 'style');
$worksheet->setCellValueByColumnAndRow(5, 2, 'time');
//合并单元格
$worksheet->mergeCells('A1:E1');
$styleArray = [
'font' => [
'bold' => true
],
'alignment' => [
'horizontal' => PhpOfficePhpSpreadsheetStyleAlignment::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);
;
$jzInfo = db('wdjz')->select();
$len = count($jzInfo);
$j = 0;
for ($i=0; $i < $len; $i++) {
$j = $i + 3; //从表格第3行开始
$worksheet->setCellValueByColumnAndRow(1, $j, $jzInfo[$i]['name']);
$worksheet->setCellValueByColumnAndRow(2, $j, $jzInfo[$i]['phone']);
$worksheet->setCellValueByColumnAndRow(3, $j, $jzInfo[$i]['radio1']);
$worksheet->setCellValueByColumnAndRow(4, $j, $jzInfo[$i]['style']);
$worksheet->setCellValueByColumnAndRow(5, $j, $jzInfo[$i]['time']);
}
$styleArrayBody = [
'borders' => [
'allBorders' => [
'borderStyle' => PhpOfficePhpSpreadsheetStyleBorder::BORDER_THIN,
'color' => ['argb' => '666666'],
],
],
'alignment' => [
'horizontal' => PhpOfficePhpSpreadsheetStyleAlignment::HORIZONTAL_CENTER,
],
];
$total_jzInfo = $len + 2;
//添加所有边框/居中
$worksheet->getStyle('A1:C'.$total_jzInfo)->applyFromArray($styleArrayBody);
$filename = 'wdjz无毒样板客户表.xlsx';
header('Content-Type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet');
header('Content-Disposition: attachment;filename="'.$filename.'"');
header('Cache-Control: max-age=0');
$writer = PhpOfficePhpSpreadsheetIOFactory::createWriter($spreadsheet, 'Xlsx');
$writer->save('php://output');
}
设置表头
首先我们引入自动加载PhpSpreadsheet库,然后实例化,设置工作表标题名称为:学生成绩表,接着设置表头内容。表头分为两行,第一行是表格的名称,第二行数表格列名称。最后我们将第一行单元格进行合并,并设置表头内容样式:字体、对齐方式等
require 'vendor/autoload.php';
use PhpOfficePhpSpreadsheetSpreadsheet;
use PhpOfficePhpSpreadsheetWriterXlsx;
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' => PhpOfficePhpSpreadsheetStyleAlignment::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);
读取数据
我们连接数据库后,直接读取学生成绩表t_student,然后for循环,设置每个单元格对应的内容,计算总成绩。注意的是表格中的数据是从第3行开始,因为第1,2行是表头占用了。
$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' => PhpOfficePhpSpreadsheetStyleBorder::BORDER_THIN,
'color' => ['argb' => '666666'],
],
],
'alignment' => [
'horizontal' => PhpOfficePhpSpreadsheetStyleAlignment::HORIZONTAL_CENTER,
],
];
$total_rows = $len + 2;
//添加所有边框/居中
$worksheet->getStyle('A1:E'.$total_rows)->applyFromArray($styleArrayBody);
如果仅是为了满足文章开头说的老板的需求,我们这个时候就可以将数据保存为Excel文件,当然这个Excel文件只保存在服务器上,然后再使用邮件等方式将Excel发送给老板就结了。
下载保存
$filename = '成绩表.xlsx';
header('Content-Type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet');
header('Content-Disposition: attachment;filename="'.$filename.'"');
header('Cache-Control: max-age=0');
$writer = PhpOfficePhpSpreadsheetIOFactory::createWriter($spreadsheet, 'Xlsx');
$writer->save('php://output');
如果你想要保存为.xls文件格式的话,可以改下header代码:
$filename = '成绩表.xlsx';
header('Content-Type: application/vnd.ms-excel');
header('Content-Disposition: attachment;filename="'.$filename.'"');
header('Cache-Control: max-age=0');
$writer = PhpOfficePhpSpreadsheetIOFactory::createWriter($spreadsheet, 'xls');
$writer->save('php://output');
PhpSpreadsheet提供了很多选项设置,接下来的文章我会专门介绍有关生成Excel的设置,如样式:字体、对齐、颜色、行高于列宽,合并与拆分、图片、日期时间、换行、函数使用等等。敬请关注。
