1、导出 Excel

$data=[
    ['name'=>'a','age'=>11],
    ['name'=>'b','age'=>22],
    ['name'=>'d','age'=>33],
];
$fileds=[
    "name"=>"名称",
    "age"=>"年龄",
];

push($data,'test',$fileds);
function push($data,$name='fage_Excel',$fields=array()){
    require_once("./Classes/PHPExcel.php");

    error_reporting(E_ALL);
    ini_set('date.timezone','PRC');
    $objPHPExcel = new \PHPExcel();
    ini_set('memory_limit', '-1');
    $username = 'a';
    /*以下是一些设置 ，什么作者  标题啊之类的*/
    $objPHPExcel->getProperties()->setCreator($username)
        ->setLastModifiedBy($username)
        ->setTitle("订单数据导出")
        ->setSubject("订单数据导出")

    $num = 0;
    foreach($fields as $k => $v){

        $objPHPExcel->setActiveSheetIndex(0)

                $v[$kk] =  str_replace(base_url(),"",$v[$kk]) ;
                $path='.'.$v[$kk];
                if($v[$kk]&&file_exists($path)){

                    $objPHPExcel->setActiveSheetIndex(0)->getRowDimension($num)->setRowHeight(80);

                }

            }
            else

    $objWriter = \PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel2007');
    ob_end_clean();
    $objWriter->save('php://output');
    exit;
}

2、导入Excel

先通过文件上传方式到服务器

php+html+js+ajax实现文件上传_php上传文件ajax-CSDN博客

读取数据

$file='test.xls';
$data=read($file);
var_dump($data);exit;
function read($file){
    require_once("./Classes/PHPExcel.php");
    // 加载Excel文件
    $objPHPExcel = PHPExcel_IOFactory::load($file);

    // 获取第一个工作表
    $sheet = $objPHPExcel->getActiveSheet();
    $rowDataAll=[];
      // 循环读取每一行数据
    foreach ($sheet->getRowIterator() as $row) {
        $rowData = array();
        // 循环读取每一列数据
        foreach ($row->getCellIterator() as $cell) {
            $rowData[] = $cell->getValue();
        }
        $rowDataAll[]=$rowData;

    }
    return $rowDataAll;
}
