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。
