php Spreadsheet_Excel_Reader读取excel文件

$reader=new spreadsheet_excel_reader();
$reader->setutfencoder('iconv');
$reader->setoutputencoding('utf-8'); //可以设置的文档编码
$reader->read($filename);

//如果以以表格形式输出我们就利用遍历

foreach ($reader->boundsheets as $k=>$sheet)
 {
    echo "n$k: $sheet";
 }

//表中的数据存储在表变量.每一个表是一个二维数组。以下是如何打印所有数据

foreach($reader->sheets as $k=>$data)
 {
    echo "nn ".$reader->boundsheets[$k]."nn";

    foreach($data['cells'] as $row)
    {
        foreach($row as $cell)
        {
            echo "$cellt";
        }
        echo "n";
    }
 }
