PhpOffice/PhpSpreadsheet读取和写入Excel
读取Excel文件，源码并将数据读取成数组$spreadsheet=\PhpOffice\PhpSpreadsheet\IOFactory::load($file['tmp_file']);//指定第一个工作表为当前$data=$spreadsheet->getSheet(0)->toArray();
PhpSpreadsheet是源码一个纯PHP编写的组件库，它使用现代PHP写法，源码代码质量和性能比PHPExcel高不少，源码完全可以替代PHPExcel（PHPExcel已不再维护）。源码使用PhpSpreadsheet可以轻松读取和写入Excel文档，源码试玩平台源码出售支持Excel的源码所有操作。
官网：poser安装：
composerrequirephpoffice/phpspreadsheet使用在项目目录下新建/public目录，源码在public目录下创建示例文件test.php，源码编辑test.php，源码用以下代码。源码
<?源码phprequire'../vendor/autoload.php';usePhpOffice\PhpSpreadsheet\Spreadsheet;usePhpOffice\PhpSpreadsheet\Writer\Xlsx;$spreadsheet=newSpreadsheet();$sheet=$spreadsheet->getActiveSheet();$sheet->setCellValue('A1','WelcometoHelloweba.');$writer=newXlsx($spreadsheet);$writer->save('hello.xlsx');运行代码，你会发现在目录下生成一个hello.xlsx文件，源码打开Excel文件，源码你会看到Excel中的源码单元格A1中有“Welcome to Helloweba.”内容。当然你可以对单元格样式诸如颜色、背景、宽度、字体等等进行设置，外卖cps源码在哪这些会在接下来的几节中讲到。
PhpSpreadsheet特性支持读取.xls，.xlsx，.html，.csv等格式文件，支持写入导出.xls，.xlsx，.html，.csv，2022年直播源码.pdf格式文件。
提供丰富的API，提供单元格样式设置、Excel表格属性设置、图表设置等等诸多功能。使用PhpSpreadsheet完全可以生成一个外观结构都满足你的Excel表格文件。
卓越的性能，尤其在PHP7上表现优异，比PHPExcel强大很多。kda股票源码
2. 使用PhpSpreadsheet将Excel导入到MySQL数据库导入Excel思路：使用PhpSpreadsheet读取Excel表格中的有用信息，然后组装成sql语句，最后批量插入到MySQL表中。
require'vendor/autoload.php';include('conn.php');//连接数据库$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');}$sql="INSERTINTO`t_student`(`name`,`chinese`,`maths`,`english`)VALUES";for($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();}worksheet->getCellByColumnAndRow(col, row)->getValue() 可以获取表格中任意单元格数据内容，col表示单元格所在的列，以数字表示，A列表示第一列，$row表示所在的行。
3. 使用PhpSpreadsheet将数据导出为Excel文件一、直播源码怎么选设置表头首先我们引入自动加载PhpSpreadsheet库，然后实例化，设置工作表标题名称为：学生成绩表，接着设置表头内容。表头分为两行，第一行是表格的名称，第二行数表格列名称。最后我们将第一行单元格进行合并，并设置表头内容样式：字体、对齐方式等。
require'vendor/autoload.php';usePhpOffice\PhpSpreadsheet\Spreadsheet;usePhpOffice\PhpSpreadsheet\Writer\Xlsx;include('conn.php');//连接数据库$spreadsheet=newSpreadsheet();$worksheet=$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($styleArray)->getFont()->setSize();$worksheet->getStyle('A2:E2')->applyFromArray($styleArray)->getFont()->setSize();二、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。
然后，我们设置整个表格样式，给表格加上边框，并且居中对齐。
$sql="SELECTid,name,chinese,maths,englishFROM`t_student`";$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']);}$styleArrayBody=['borders'=>['allBorders'=>['borderStyle'=>\PhpOffice\PhpSpreadsheet\Style\Border::BORDER_THIN,'color'=>['argb'=>''],],],'alignment'=>['horizontal'=>\PhpOffice\PhpSpreadsheet\Style\Alignment::HORIZONTAL_CENTER,],];$total_rows=$len+2;//添加所有边框/居中$worksheet->getStyle('A1:E'.$total_rows)->applyFromArray($styleArrayBody);三、下载保存强制浏览器下载数据并保存为Excel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');如想要保存为.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');$writer=\PhpOffice\PhpSpreadsheet\IOFactory::createWriter($spreadsheet,'xls');$writer->save('php://output');4. 详解PhpSpreadsheet设置单元格PhpSpreadsheet提供了丰富的API接口，可以设置诸多单元格以及文档属性，包括样式、、日期、函数等等诸多应用，总之你想要什么样的Excel表格，PhpSpreadsheet都能做到。
引入了正确的文件并实例化:usePhpOffice\PhpSpreadsheet\Spreadsheet;$spreadsheet=newSpreadsheet();$worksheet=$spreadsheet->getActiveSheet();字体第1行代码将A7至B7两单元格设置为粗体字，Arial字体，号字；第2行代码将B1单元格设置为粗体字。
$spreadsheet->getActiveSheet()->getStyle('A7:B7')->getFont()->setBold(true)->setName('Arial')->setSize();;$spreadsheet->getActiveSheet()->getStyle('B1')->getFont()->setBold(true);颜色将文字颜色设置为红色
composerrequirephpoffice/phpspreadsheet0可以将加载到Excel中
composerrequirephpoffice/phpspreadsheet1列宽将A列宽度设置为（字符）:
composerrequirephpoffice/phpspreadsheet2如果需要自动计算列宽，可以这样：
composerrequirephpoffice/phpspreadsheet3设置默认列宽为:
composerrequirephpoffice/phpspreadsheet4行高设置第行行高为pt：
composerrequirephpoffice/phpspreadsheet5设置默认行高:
composerrequirephpoffice/phpspreadsheet6对齐将A1单元格设置为水平居中对齐:
composerrequirephpoffice/phpspreadsheet7合并将A到E合并为一个单元格:
composerrequirephpoffice/phpspreadsheet8拆分将合并后的单元格拆分:
composerrequirephpoffice/phpspreadsheet9边框将B2至G8的区域添加红色边框:
<?phprequire'../vendor/autoload.php';usePhpOffice\PhpSpreadsheet\Spreadsheet;usePhpOffice\PhpSpreadsheet\Writer\Xlsx;$spreadsheet=newSpreadsheet();$sheet=$spreadsheet->getActiveSheet();$sheet->setCellValue('A1','WelcometoHelloweba.');$writer=newXlsx($spreadsheet);$writer->save('hello.xlsx');0工作表标题设置当前工作表标题:
<?phprequire'../vendor/autoload.php';usePhpOffice\PhpSpreadsheet\Spreadsheet;usePhpOffice\PhpSpreadsheet\Writer\Xlsx;$spreadsheet=newSpreadsheet();$sheet=$spreadsheet->getActiveSheet();$sheet->setCellValue('A1','WelcometoHelloweba.');$writer=newXlsx($spreadsheet);$writer->save('hello.xlsx');1日期时间设置日期格式:
<?phprequire'../vendor/autoload.php';usePhpOffice\PhpSpreadsheet\Spreadsheet;usePhpOffice\PhpSpreadsheet\Writer\Xlsx;$spreadsheet=newSpreadsheet();$sheet=$spreadsheet->getActiveSheet();$sheet->setCellValue('A1','WelcometoHelloweba.');$writer=newXlsx($spreadsheet);$writer->save('hello.xlsx');2换行使用\n进行单元格内换行，相当于(ALT+"Enter"):
<?phprequire'../vendor/autoload.php';usePhpOffice\PhpSpreadsheet\Spreadsheet;usePhpOffice\PhpSpreadsheet\Writer\Xlsx;$spreadsheet=newSpreadsheet();$sheet=$spreadsheet->getActiveSheet();$sheet->setCellValue('A1','WelcometoHelloweba.');$writer=newXlsx($spreadsheet);$writer->save('hello.xlsx');3超链接将单元格设置为超链接形式:
<?phprequire'../vendor/autoload.php';usePhpOffice\PhpSpreadsheet\Spreadsheet;usePhpOffice\PhpSpreadsheet\Writer\Xlsx;$spreadsheet=newSpreadsheet();$sheet=$spreadsheet->getActiveSheet();$sheet->setCellValue('A1','WelcometoHelloweba.');$writer=newXlsx($spreadsheet);$writer->save('hello.xlsx');4使用函数使用SUM计算B5到C5之间单元格的总和。其他函数同理：最大数(MAX)，最小数(MIN)，平均值(AVERAGE):
<?phprequire'../vendor/autoload.php';usePhpOffice\PhpSpreadsheet\Spreadsheet;usePhpOffice\PhpSpreadsheet\Writer\Xlsx;$spreadsheet=newSpreadsheet();$sheet=$spreadsheet->getActiveSheet();$sheet->setCellValue('A1','WelcometoHelloweba.');$writer=newXlsx($spreadsheet);$writer->save('hello.xlsx');5设置文档属性可以设置Excel文档属性:
<?phprequire'../vendor/autoload.php';usePhpOffice\PhpSpreadsheet\Spreadsheet;usePhpOffice\PhpSpreadsheet\Writer\Xlsx;$spreadsheet=newSpreadsheet();$sheet=$spreadsheet->getActiveSheet();$sheet->setCellValue('A1','WelcometoHelloweba.');$writer=newXlsx($spreadsheet)åºäºphpä¸ä½¿ç¨excelçç®åä»ç»
