Question

require_once ('PHPExcel.php');
require_once ('PHPExcel/IOFactory.php');
require_once ('PHPExcel/Reader/Excel5.php');

if($_POST['leadExcel'] == "true")
{

$filename = $_FILES['inputExcel']['name'];

//自己设置的上传文件存放路径
$filePath = '../../upfile/';
$str = "";
//注意设置时区
$time=date("y-m-d-H-i-s");//去当前上传的时间
//获取上传文件的扩展名
$extend=strrchr($filename,'.');
//上传后的文件名
$name=$time.$extend;
$uploadfile=$filePath.$name;//上传后的文件名地址
//move_uploaded_file() 函数将上传的文件移动到新位置。若成功，则返回 true，否则返回 false。

if($result) //如果上传文件成功，就执行导入excel操作
