下载插件:PHP_XLSXWriter
PHP_XLSXWriter是一个小而强悍的Excel读写插件,它并没有PHPExcel功能丰富,很多高级操作比如冻结表头,并不具备,但是它导出速度非常快,非常适合于数据量特别大,报表格式不是很复杂的导出需求。

1.TestController.php

 /**
     * 用户数据导出
     * @return String
     * */
    public function actionExport(){
        if(Yii::$app->request->isPost) {
            $post = Yii::$app->request->post();
            $data[] = ['id'=>1,'username'=>'earnest','nickname'=>'御风','dept_name'=>'信息部'];
            
            $this->xlsWriteExcel($post['field'], $post['title'], $data['data'], '用户信息_');
        }

        $header = [
            'id' => 'ID',
            'username' => '用户名',
            'nickname' => '昵称',
            'created_at' => '创建时间',
            'updated_at' => '更新时间',
            'dept_name' => '部门名称',
            'status' => '状态'
        ];

        return $this->render('export',[
            'header' => $header,
            'url'=>Yii::$app->request->get('url').'export',
            'param'=>str_replace('"',"'",json_encode(Yii::$app->request->get()))
        ]);
    }

public function xlsWriteExcel($field,$header,$data,$fileName='自定义导出'){
    require_once Yii::getAlias('@vendor') . '/phpxlsxwriter/vendor/autoload.php';
    header("Content-Type: text/html;charset=utf-8");
    error_reporting(E_ALL);
    set_time_limit(0);
    ob_start();
    $sheet = 'Sheet1';
    $writer = new \XLSXWriter();
    $field = explode(',',$field);
    $header = explode(',',$header);
    $header = array_fill_keys($header,"string");
    $styles1 = array(
        'font'=>'宋体','font-size'=>10,'font-style'=>'bold', 'fill'=>'#eee',
        'halign'=>'center','border'=>'left,right,top,bottom'
    );
    $title = array_keys($header);
    $writer->writeSheetRow($sheet, $title, $styles1);
    if(!empty($data)){
        foreach ($data as $k=>$v){
            foreach ($field as $k1=>$v1){
                if(isset($v[$v1])){
                    $rows[$k1] = $v[$v1];
                }else{
                    $rows[$k1] = '';
                }
            }
            $writer->writeSheetRow($sheet, $rows, $styles1);
        }
    }
    $filename = $fileName.date('YmdHis',time()).'.xlsx';
    $tempFile = tempnam(sys_get_temp_dir(), 'excel');
    $writer->writeToFile($tempFile);
    header('Content-Type: application/octet-stream');
    header('Content-Disposition: attachment; filename=' . $filename);
    readfile($tempFile);
    unlink($tempFile);
}
