phpspreadshhet 读取，导出

安装

    composer require fan1992/phpspreadsheet

使用示例

    use Fan1992\Phpspreadsheet\Excel;
    $excel = new Excel();

读取文档（默认只读取第一个sheet）

    $data = $excel->read('./test.xlsx');
    print_r($data);

一次读取多个sheet

    $excel->sheetNames = ['data_a'=>'表1','data_b'=>'表2','data_c'=>'Sheet3'];
    $data = $excel->read('./test.xlsx');
    print_r($data);

一次读取所有sheet

    $excel = new Excel();
    $excel->autoReadAllSheets = true;
    $data = $excel->read('./test.xlsx');
    print_r($data);

导出

    $header = ['提提1', 'title2', '标题3', '测试测试']; //表头，即第一行
    $data = [//具体数据，支持多维数组（合并单元格）
        ['12', ['阿斯顿发','asdf','2019-06-19'], '是的', '沙箱'],
        ['撒发顺丰的', ['1','23','撒旦法师'], '2019-06-19', 'asdasdfas']
    ];
    $width = [30,0,40,60]; //列宽度，为0或没有则自动适应
    $excel->export($data, $header,'test'.time(),null, 'mysheet', $width);

导出多个sheet

    $excel1Data = [
        'data'      => [
            ['12', ['阿斯顿发', 'asdf', '2019-06-19'], '是的', '沙箱'],
            ['asd', ['阿斯顿发', '22', '2019-06-19'], '是', '沙asdf箱'],
        ],
        'header'    => ['header1', '标题2', '333', '超级长超级长超级长超级长超级长超级长超级长的标题'],
        'sheetName' => '1211sheet1',
        'width'     => [5, 0, 5]
    ];
    $excel2Data = [
        'data'      => [
            ['12', ['阿斯顿发', 'asdf', '2019-06-19'], '是的', '沙箱'],
            ['asd', ['阿斯顿发', '22', '2019-06-19'], '是', '沙asdf箱'],
        ],
        'header'    => ['header1', '标题2', '333', '超级长超222222级长超级长超级长超级长超级长超级长的标题'],
        'sheetName' => '',
        'width'     => []
    ];
    $excel3Data = [
        'data'      => [
            ['12', ['阿斯顿发', 'asdf', '2019-06-19'], '是的', '沙333箱'],
            ['asd', ['阿斯顿发', '22', '2019-06-19'], '是3333', '沙asdf箱'],
        ],
        'header'    => ['header1', '标题2', '333', '超级长超级长超3333级长超级长超级长超级长超级长的标题'],
        'sheetName' => '导出sheet3',
        'width'     => []
    ];
    $data       = [$excel1Data, $excel2Data, $excel3Data];
    $excel->mutiSheetExport($data, 'muti' . time(), Sheet::TYPE_XLSX);

其它

    $readFirstLine = false;//是否读取首行
    $down = true; //是否直接下载，false则保存文件在服务器上
    
    支持导出格式：xls，xlsx
