PhpSpreadsheet的简单使用

Posted 2022-07-30 woods1815

 

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：

   https://github.com/PHPOffice/PhpSpreadsheet

 

2、excel文件导出

/**
 * excel文件导出
 */
function export()

    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
 */
function save()

    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
 */
function read()

    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。
