php使用phpexcel插件实现导入导入道出功能
首先下载phpexcel插件下载结果如下:

然后在功能模块从PHPExcel目录导PHPExcel.php类文件实例化excel读取类
导入功能:
//判断导入文件类别
if ($type=="xlsx" || $type=="csv")
{
import("Vendor.PHPExcel"); //从PHPExcel目录导PHPExcel.php类文件
$PHPExcel=new \PHPExcel();
import("Vendor.PHPExcel.Reader.Excel2007");
//实例化excel读取类
$PHPReader = new \PHPExcel_Reader_Excel2007();
//若读取失败,则实例化excel5读取类
if(!$PHPReader->canRead($path)){
$PHPReader = new \PHPExcel_Reader_Excel5();
}
// $reader = \PHPExcel_IOFactory::createReader('Excel2007');
$PHPExcel = $PHPReader->load($path); // 载入excel文件
$sheet = $PHPExcel->getSheet(0); // 读取第一個工作表
$highestRow = $sheet->getHighestRow(); // 取得总行数
$highestColumm = $sheet->getHighestColumn(); // 取得总列数
$dataFile["num"]=intval($highestRow-1); //添加数据条数
$id=M("data_file")->add($dataFile);
/** 循环读取并插入每个单元格的数据 */
if ($highestRow > 1)
{
//获取输入的字段 表的第一行
for ($row = 1; $row <= 1 ; $row++)
{
for ($column = 'A'; $column <= $highestColumm; $column++)
{
$string = $sheet->getCell($column.$row)->getValue();
$data[$column ] = $string;//单元格值放进数组
}
}
//获取输入信息 表的第二行以后数据
for ($row = 2; $row <= $highestRow ; $row++)
{
for ($column = 'A'; $column <= $highestColumm; $column++)
{
$sheet_value = $sheet->getCell($column.$row)->getValue()?$sheet->getCell($column.$row)->getValue():"null";
$dataset[$data[$column]] =$sheet_value;//单元格值放进数组
}
$dataset["uid"]=$uid; //导入这些数据用户的id
$dataset["fid"]=$id; //数据文件id
$dataset["time"]=time();
//$array[$dataset["phone"]]=$dataset;
$array[]=$dataset;
}
}else{
return 2;
}
}
// 导入txt文件
if ($type=="txt")
{
$f= fopen($path,"r");
$num=0;
while (!feof($f))
{
$num++;
$line = fgets($f);
$array[$num]["phone"]=substr(htmlspecialchars($line),0,11);
$array[$num]["uid"]=$uid; //导入这些数据用户的id
}
$len=count($array);
$dataFile["num"]=$len; //添加数据条数
$id=M("data_file")->add($dataFile);
foreach ($array as $key => $value)
{
$value["time"]=time();
$array[$key]=$value;
}
}
$array=array_merge($array);
$data=array_chunk($array,2000);
$count_data=count($data);
$data_list = M('data_list');
$i=0;
//插入数据到数据库
while ($i<$count_data) {
$users=$data_list->addAll($data[$i]);
$i++;
}
unlink($path);
return 1;
注意:导入时文件路径要是真实路径临时路径会出问题
