PHP导入导出Excel文件的方法

require_once 'Excel/reader.php';
$data = new Spreadsheet_Excel_Reader();
$data->setOutputEncoding('gbk');
$data->read('test.xls');
for ($i = 1; $i <= $data->sheets[0]['numRows']; $i++) {
    for ($j = 1; $j <= $data->sheets[0]['numCols']; $j++) {
        echo """.$data->sheets[0]['cells'][$i][$j]."",";
    }
    echo "n";
}
?>

require_once 'reader.php';

// ExcelFile($filename, $encoding);
$data = new Spreadsheet_Excel_Reader();

// Set output Encoding.
$data->setOutputEncoding('gbk');

//”data.xls”是指要导入到mysql中的excel文件
$data->read('data.xls');

@ $db = mysql_connect('localhost', 'root', '123456') or
       die("Could not connect to database.");//连接数据库
mysql_query("set names 'gbk'");//输出中文
mysql_select_db('mydb');       //选择数据库
error_reporting(E_ALL ^ E_NOTICE);

for ($i = 1; $i <= $data->sheets[0]['numRows']; $i++) {
//以下注释的for循环打印excel表数据
/*
for ($j = 1; $j <= $data->sheets[0]['numCols']; $j++) {
            echo """.$data->sheets[0]['cells'][$i][$j]."",";
           }
           echo "n";
