Yii2实现Excel大量数据快速导出
作者：互联网
效果图：
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);
}

var url = $('#url').val();
Post("<?php echo Url::toRoute('"+url+"');?>",[
{ name:'field',value:field.join(',')},
{ name:'title',value:title.join(',')},
{ name:'param',value:$('#param').val()}

});
/*

*参数： URL 跳转地址 PARAMTERS 参数
*/
function Post(URL, PARAMTERS) {
//创建form表单
var temp_form = document.createElement("form");
temp_form.action = URL;
//如需打开新窗口，form的target属性要设置为'_blank'

});
完毕！
