由于PHPExcel已经不再维护，PhpSpreadsheet是PHPExcel的下一个版本。PhpSpreadsheet是一个用纯PHP编写的库，并引入了命名空间，PSR规范等。这里简单介绍下PhpSpreadsheet的导入导出功能。

1、安装

使用composer安装：

composer require phpoffice/phpspreadsheet

GitHub下载：

2、excel文件导出

/**

* excel文件导出*/

functionexport()

{require_once __DIR__ . ‘/vendor/autoload.php‘;$data =[

[‘title1‘ => ‘111‘, ‘title2‘ => ‘222‘],[‘title1‘ => ‘111‘, ‘title2‘ => ‘222‘],[‘title1‘ => ‘111‘, ‘title2‘ => ‘222‘]

];$title = [‘第一行标题‘, ‘第二行标题‘];//Create new Spreadsheet object

$spreadsheet = new\PhpOffice\PhpSpreadsheet\Spreadsheet();$sheet = $spreadsheet->getActiveSheet();//方法一，使用 setCellValueByColumnAndRow

//表头

//设置单元格内容

foreach ($title as $key => $value) {//单元格内容写入

$sheet->setCellValueByColumnAndRow($key + 1, 1, $value);

}$row = 2; //从第二行开始

foreach ($data as $item) {$column = 1;foreach ($item as $value) {//单元格内容写入

$sheet->setCellValueByColumnAndRow($column, $row, $value);$column++;

}$row++;

}//方法二，使用 setCellValue

//表头

//设置单元格内容

$titCol = ‘A‘;foreach ($title as $key => $value) {//单元格内容写入

$sheet->setCellValue($titCol . ‘1‘, $value);$titCol++;

}$row = 2; //从第二行开始

foreach ($data as $item) {$dataCol = ‘A‘;foreach ($item as $value) {//单元格内容写入

$sheet->setCellValue($dataCol . $row, $value);$dataCol++;

}$row++;

}//Redirect output to a client’s web browser (Xlsx)

header(‘Content-Type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet‘);header(‘Content-Disposition: attachment;filename="01simple.xlsx"‘);header(‘Cache-Control: max-age=0‘);//If you‘re serving to IE 9, then the following may be needed

header(‘Cache-Control: max-age=1‘);//If you‘re serving to IE over SSL, then the following may be needed

header(‘Expires: Mon, 26 Jul 1997 05:00:00 GMT‘); //Date in the past

header(‘Last-Modified: ‘ . gmdate(‘D, d M Y H:i:s‘) . ‘ GMT‘); //always modified

header(‘Cache-Control: cache, must-revalidate‘); //HTTP/1.1

header(‘Pragma: public‘); //HTTP/1.0

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

}

结果：

3、excel文件保存到本地

/**

* excel文件保存到本地*/

functionsave()

{require_once __DIR__ . ‘/vendor/autoload.php‘;$data =[

[‘title1‘ => ‘111‘, ‘title2‘ => ‘222‘],[‘title1‘ => ‘111‘, ‘title2‘ => ‘222‘],[‘title1‘ => ‘111‘, ‘title2‘ => ‘222‘]

];$title = [‘第一行标题‘, ‘第二行标题‘];//Create new Spreadsheet object

$spreadsheet = new\PhpOffice\PhpSpreadsheet\Spreadsheet();$sheet = $spreadsheet->getActiveSheet();//表头

//设置单元格内容

$titCol = ‘A‘;foreach ($title as $key => $value) {//单元格内容写入

$sheet->setCellValue($titCol . ‘1‘, $value);$titCol++;

}$row = 2; //从第二行开始

foreach ($data as $item) {$dataCol = ‘A‘;foreach ($item as $value) {//单元格内容写入

$sheet->setCellValue($dataCol . $row, $value);$dataCol++;

}$row++;

}//Save

$writer = \PhpOffice\PhpSpreadsheet\IOFactory::createWriter($spreadsheet, ‘Xlsx‘);$writer->save(‘01simple.xlsx‘);

}

4、读取excel文件内容

/**

* 读取excel文件内容*/

functionread()

{require_once __DIR__ . ‘/vendor/autoload.php‘;$inputFileName = dirname(__FILE__) . ‘/01simple.xlsx‘;$spreadsheet = \PhpOffice\PhpSpreadsheet\IOFactory::load($inputFileName);//方法二

$sheetData = $spreadsheet->getActiveSheet()->toArray(null, true, true, true);return $sheetData;

}

结果：

可能出现的问题：

1、Fatal error: Uncaught Error: Class ‘PhpOffice\PhpSpreadsheet\Spreadsheet‘ not found

这是因为没有自动加载。可以手动引入加载文件。

require_once __DIR__ . ‘/vendor/autoload.php‘;

或者：

require_once __DIR__ . ‘/vendor/phpoffice/phpspreadsheet/src/Bootstrap.php‘;

2、Fatal error: Interface ‘Psr\SimpleCache\CacheInterface‘ not found

这是因为没有psr文件，缺少simple-cache模块。如果使用composer安装的话会自动生成。没有的话可以手动下载。
