php导出excel（xls或xlsx）（解决长数字显示问题）

1）demo

$titles                = array('订单号','商品结算码','合同号','供应商名称','专柜','商品名称','商品货号','商品单价','商品总价','供应商结算金额','商品数量','商品促销优惠','平台优惠抵扣','品牌订单优惠抵扣');

//导出准备
ob_get_clean();
ob_start();
echo implode("\t", $titles),"\n";

$currencyModel      = app::get('ectools')->model('currency');
foreach ($lists as $key=>$value) {
$row                             = array();
$row['order_id']                = html_entity_decode("".$value['order_id']);
$row['supplier_num']            = $value['supplier_num'];
$row['agreement_code']            = $value['agreement_code'];
$row['supplier_name']            = $value['supplier_name'];
$row['shoppe_name']                = $value['shoppe_name'];
$row['name']                    = $value['name'];
$row['bn']                        = $value['bn'];
$row['price']                   = $value['price'];
$row['nums']                    = $value['nums'];
$row['g_price']                 = $value['g_price'];
$row['settlement_amount']       = $value['settlement_amount'];
$row['goods_amount_off']         = $value['goods_amount_off'];
$row['amount_off']                 = $value['amount_off'];
$row['brand_amount_off']         = $value['brand_amount_off'];

echo implode("\t", $row),"\n";
}

header('Content-Disposition: attachment; filename='.$filename);
header('Accept-Ranges:bytes');
header('Content-Length:' . ob_get_length());
header('Content-Type:application/vnd.ms-excel');
ob_end_flush();

2）格式选择

需要导出xls的话，用

header('Content-Type:application/vnd.ms-excel');

需要导出xlsx的话，用

header('Content-Type:application/vnd.openxmlformats-officedocument.spreadsheetml.sheet');

xls和xlsx的区别的话，是储存数据量大小的问题，xls只可以保存大概5、6w数据，xlsx可以100w左右

3）长数字完整显示解决办法

$row['order_id']                = html_entity_decode("".$value['order_id']);

就是先拼上html 特殊字符 ，再转回去的意思

PS:这个办法，是从PHPExcel上逆回去找到的

我把PHPExcel生成的数字复制到txt文件里，再解释它是什么东东，然后就发现这个东西了
