/*** * 导出下载excel * @param [array] $array [要转换excel数组] */ public function export_csv($array){ $temp = ''; foreach ($array as $value) { foreach ($value as $k => $val) { $value[$k] = iconv('utf-8','gb2312',$value[$k]); } $temp .= implode(",",$value)."\n"; //用英文“逗号”分开，获取值 } # 获取name,age做标题【这里我没有想到更好的方法，做个flag以便以后更加完善】 ## 就是要取出 ‘name’,'age' 这两个key $keyname = array_keys($array[0])[0] . ',' . array_keys($array[0])[1] ."\n"; $string = $keyname. $temp;//拼接 $filename = date('Ymd').'.csv'; //设置文件名 header("Content-type:text/csv"); header("Content-Disposition:attachment;filename=".$filename); header('Cache-Control:must-revalidate,post-check=0,pre-check=0'); header('Expires:0'); header('Pragma:public'); echo $string; }
