TP5使用phpexce上傳導入csv文件

前端上傳使用layui.upload組件,具體參考Layui手冊

php:

//主邏輯
//限制上傳表格類型
$file_type = $_FILES['excel_import']['type'];
if ($file_type!='application/vnd.ms-excel') {
   return [RESULT_ERROR,'上傳失敗，只能上傳excel表格!'];
}
if (is_uploaded_file($_FILES['excel_import']['tmp_name'])) {//判斷文件上傳是否成功
   $data = get_excel_data($_FILES['excel_import']['tmp_name'],2,0,'csv');
   //TODO 執行導入後的邏輯
}else{
   return [RESULT_ERROR, '請選擇文件後導入'];
}

//get_excel_data
/**
 * 讀取excel返回數據
 */
function get_excel_data($file_url = '', $start_row = 1, $start_col = 0, $type = 'xls')
{
    vendor('phpoffice/phpexcel/Classes/PHPExcel');
    //此處邏輯爲解決導入xls和csv的衝突
    if( $type=='xlsx'||$type=='xls' ){
        $objPHPExcel = PHPExcel_IOFactory::load($file_url);
    }else if( $type=='csv' ){
        $objReader = PHPExcel_IOFactory::createReader('CSV')
            ->setDelimiter(',')
            ->setInputEncoding('GBK') //不設置將導致中文列內容返回boolean(false)或亂碼
            ->setEnclosure('"')
            ->setSheetIndex(0);
        $objPHPExcel = $objReader->load($file_url);
    }else{
        die('Not supported file types!');
    }
    $objWorksheet       = $objPHPExcel->getActiveSheet();
    $highestRow         = $objWorksheet->getHighestDataRow(); 
    $highestColumn      = $objWorksheet->getHighestDataColumn(); 
   $highestColumnIndex  = PHPExcel_Cell::columnIndexFromString($highestColumn); 
    
    $excel_data = [];
    
    for ($row = $start_row; $row <= $highestRow; $row++)
    {
        for ($col = $start_col; $col < $highestColumnIndex; $col++)
        {
            $excel_data[$row][] =(string)$objWorksheet->getCellByColumnAndRow($col, $row)->getValue();
        }
    }

    return $excel_data;
