读取：

load($filename);
//获取表中的第一个工作表，如果要获取第二个，把0改为1，依次类推

$currentSheet=$PHPExcel->getSheet(0);
//获取总列数
$allColumn=$currentSheet->getHighestColumn();
//获取总行数
$allRow=$currentSheet->getHighestRow();
//循环获取表中的数据，$currentRow表示当前行，从哪行开始读取数据，索引值从0开始
for($currentRow=1;$currentRow<=$allRow;$currentRow++){
    //从哪列开始，A表示第一列
    for($currentColumn='A';$currentColumn<=$allColumn;$currentColumn++){
        //数据坐标
        $address=$currentColumn.$currentRow;
        //读取到的数据，保存到数组$arr中
        $data[$currentRow][$currentColumn]=$currentSheet->getCell($address)->getValue();
    }
}
echo "
";
var_dump($data);
echo "
";

导出：

getActiveSheet()->setCellValue("$letter[$i]1","$tableheader[$i]");
}

//表格数组
$data = array(
    array('1','小王','男','20','100'),
    array('2','小李','男','20','101'),
    array('3','小张','女','20','102'),
    array('4','小赵','女','20','103')
);
//填充表格信息
for ($i = 2;$i <= count($data) + 1;$i++) {
    $j = 0;
    foreach ($data[$i - 2] as $key=>$value) {
        $excel->getActiveSheet()->setCellValue("$letter[$j]$i","$value");
        $j++;
    }
}

//创建Excel输入对象
