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";
}
}
