导入功能控制器的代码
public function daoru(){
$file = $_FILES['upload']['tmp_name'][0];
$data = $this->import_excel($file);
var_dump($data);
}
private function import_excel($file){
// 判断文件是什么格式
$type = pathinfo($file);
$type = strtolower($type["extension"]);
$type=$type==='csv' ? $type : 'Excel5';
ini_set('max_execution_time', '0');
Vendor('PHPExcel176.PHPExcel');
// 判断使用哪种格式
$objReader = \PHPExcel_IOFactory::createReader($type);
$objPHPExcel = $objReader->load($file);
$sheet = $objPHPExcel->getSheet(0);
// 取得总行数
$highestRow = $sheet->getHighestRow();
// 取得总列数
$highestColumn = $sheet->getHighestColumn();
//循环读取excel文件,读取一条,插入一条
$data=array();
//从第一行开始读取数据
for($j=3;$j<=$highestRow;$j++){
//从A列读取数据
for($k='A';$k<=$highestColumn;$k++){
// 读取单元格
$data[$j][]=$objPHPExcel->getActiveSheet()->getCell("$k$j")->getValue();
}
}
return $data;
}这里获得excel文件的数据内容，可以循环插入数据库中
