php使用phpexcel导出文件

首先需要去官网https://github.com/PHPOffice/PHPExcel/下载PHPExcel

代码如下：

<?php
date_default_timezone_set('PRC');
/**
 * 导出提现，充值记录
 * */
function exportWalletStatAction(){
    $body = [
        [
            'order_id'=>1,
            'money'=>2222,
        ],
        [
            'order_id'=>2,
            'money'=>3333,
        ]
    ];

    $head = [['订单号', '金额']];
    $needField = ['order_id','money'];
    $body = filterFiels($body,$needField);
    //导出文件的数据
    $fileName = 'test';
    export($fileName, $head, $body);
}
/**
 * 得到需要导出的字段
 * @return string
 */
function filterFiels($body, $needField)
{
    if (!is_array($body) || !count(array($body))) {
        $this->export();
    }
    $exportData = [];
    if (is_array($body) && count($body)) {
        foreach ($body as $key => $val) {
            foreach ($needField as $needVal) {
                if(isset($val[$needVal])){
                    $exportData[$key][$needVal] = $val[$needVal];
                }
            }
        }
    }
    return $exportData;
}

    }

    } else {

            $fileName = $fileName . '_' . date('ymdHis');
        }
    }
    $fileName .= '.xls';
    foreach ($data as $key => $val) {
        foreach ($val as $k => $v) {
            if (strpos($v, '=') === 0) {
                $val[$k] = "\t" . $v;
                $data[$key] = $val;
            }
        }
    }
    download($data, $fileName);
