PHPExcel導出功能詳解

從github下載PHPExcel：PHPExcel

將下載好的PHPExcel文件夾跟PHPExcel放置在框架中的Vendor目錄下，注意目錄的結構，按照我的代碼來基本上直接引用就能使用，附上結構，如下圖：

1、如果使用Ajax請求：

Html代碼部分：

<form class="layui-form " method="post">
    <div class="layui-input-inline w150">
        <select name="status" id="sel">
            <option value="">選擇狀態</option>
            <option value="0" {if condition="$param['status'] eq '0'"}selected {/if}>未審覈</option>
            <option value="1" {if condition="$param['status'] eq '1'"}selected {/if}>已審覈</option>
        </select>
    </div>
    <div class="layui-input-inline w150">
        <select name="group" id="group">
            <option value="">選擇會員組</option>
            {volist name="group_list" id="vo"}
            <option value="{$vo.group_id}" {if condition="$param['group'] eq $vo.group_id"}selected {/if}>{$vo.group_name}</option>
            {/volist}
        </select>
    </div>

    <div class="layui-input-inline w320">
        <input size="16" type="text" value="{$start_time}" id="datetimeStart" readonly class="form_datetime" name="start_time" placeholder="請選擇開始時間" style="height: 38px;" />
        -
        <input size="16" type="text" value="{$end_time}" id="datetimeEnd" readonly class="form_datetime" name="end_time" placeholder="請選擇結束時間" style="height: 38px;" />
    </div>

    <div class="layui-input-inline">
        <input type="text" autocomplete="off" placeholder="請輸入搜索條件" class="layui-input" name="wd" value="{$param['wd']}">
    </div>
    <button class="layui-btn mgl-20 j-search" >查詢</button>
    <button class="layui-btn mgl-20" type="button" id="btnExport" onclick="excel()">導出</button>
</form>

Js部分代碼：

//Excel導出事件
function excel()
{
    var status = $("#sel option:selected").val();
    var group = $("#group option:selected").val();
    var start_time = $('#datetimeStart').val();
    var end_time = $('#datetimeEnd').val();
    $.ajax({
        url: "{:url('admin/user/export')}",
        data: {status:status,group:group,start_time:start_time,end_time:end_time},
        type: 'post',
        dataType: 'json',
        success: function (ret) {
            var $a = $("<a>");
            $a.attr("href",ret.file);
            $("body").append($a);
            $a.attr("download","file.xls");
            $a[0].click();
            $a.remove();

            if (ret.code == -1) {
                alert(ret.msg);
            } else if (ret.code == 1) {
                window.location.href = "{:url('admin/user/data')}";
            }
        },
        error: function () {
            alert('請求失敗');
        }
    })
}

封裝Excel導出(我封裝到common.php)，代碼如下：

function exportExcel($title=array(), $data=array(), $fileName='',$sheet='', $savePath='./', $isDown=false)
{
//    Loader::import('PHPExcel.PHPExcel');
//    Loader::import('PHPExcel.PHPExcel.IOFactory');
    vendor("PHPExcel.PHPExcel");
    vendor("PHPExcel.PHPExcel.IOFactory");
    $obj = new \PHPExcel();

    //橫向單元格標識
    $cellName = array('A', 'B', 'C', 'D', 'E', 'F', 'G', 'H', 'I', 'J', 'K', 'L', 'M', 'N', 'O', 'P', 'Q', 'R', 'S', 'T', 'U', 'V', 'W', 'X', 'Y', 'Z', 'AA', 'AB', 'AC', 'AD', 'AE', 'AF', 'AG', 'AH', 'AI', 'AJ', 'AK', 'AL', 'AM', 'AN', 'AO', 'AP', 'AQ', 'AR', 'AS', 'AT', 'AU', 'AV', 'AW', 'AX', 'AY', 'AZ');

    $obj->getActiveSheet(0)->setTitle($sheet);   //設置sheet名稱
    $_row = 1;   //設置縱向單元格標識
    if($title){
        $_cnt = count($title);
        // $obj->getActiveSheet(0)->mergeCells('A'.$_row.':'.$cellName[$_cnt-1].$_row);   //合併單元格
        // $obj->setActiveSheetIndex(0)->setCellValue('A'.$_row, '數據導出：'.date('Y-m-d H:i:s'));  //設置合併後的單元格內容
        // $_row++;
        $i = 0;
        foreach($title AS $v){   //設置列標題
            $obj->setActiveSheetIndex(0)->setCellValue($cellName[$i].$_row, $v);
            $i++;
        }
        $_row++;
    }

    //填寫數據
    if($data){
        $i = 0;
        foreach($data AS $_v){
            $j = 0;
            foreach($_v AS $_cell){
                $obj->getActiveSheet(0)->setCellValue($cellName[$j] . ($i+$_row), $_cell);
                $j++;
            }
            $i++;
        }
    }

    //文件名處理
    if(!$fileName){
        $fileName = uniqid(time(),true);
    }
    header('Content-Type: application/vnd.ms-excel');
    header("Content-Disposition:attachment;filename=$fileName.xls");
    $objWrite = \PHPExcel_IOFactory::createWriter($obj, 'Excel2007');
    ob_start();
    $objWrite->save('php://output');
    $xlsData = ob_get_contents();
    ob_end_clean();

    $response =  array(
        'code' => '1',
        'file' => "data:application/vnd.ms-excel;base64,".base64_encode($xlsData),
        'msg'=>'導出成功'
    );
    return json_encode($response);
}

PHP代碼部分：

/**
 * Excel導出
 * @throws \PHPExcel_Exception
 * @throws \PHPExcel_Reader_Exception
 * @throws \PHPExcel_Writer_Exception
 */
public function export()
{
    if(Request()->isAjax()){
        $param = input('post.');
        $res = $this->call($param);
        // Excel導出部分
        $title = ['用戶名稱','狀態','積分','上次登錄時間','上次登錄IP','登錄次數'];
        $data = [];
        foreach($res['list'] as $k=>$v){
            $arr = [
                'user_name'             => $v['user_name'],
                'user_status'           => $v['user_status'],
                'user_points'           => $v['user_points'],
                'user_last_login_time'  => $v['user_last_login_time'],
                'user_last_login_ip'    => $v['user_last_login_ip'],
                'user_login_num'        => $v['user_login_num']
            ];
            $data[] = $arr;
        }

        $result = exportExcel($title,$data,'用戶名單'.date('Y-m-d'),'用戶名單','./',true);
        die($result);
    }else{
        die(json_encode(array('code'=>-1,'msg'=>'導出失敗，請刷新重試')));
    }

}

/**
 * data()、export()方法公共條件
 * @param $param
 */
public function call($param)
{
    if(!empty($param['start_time']) && !empty($param['end_time'])){
        if(strtotime($param['start_time']) > strtotime($param['end_time'])){
            return $this->error('開始時間必須小於結束時間');
        }
    }
    $param['page'] = intval($param['page']) <1 ? 1 : $param['page'];
    $param['limit'] = intval($param['limit']) <1 ? $this->_pagesize : $param['limit'];

    $where=[];
    if(in_array($param['status'],['0','1'],true)){
        $where['user_status'] = $param['status'];
    }
    if(!empty($param['group'])){
        $where['group_id'] = $param['group'];
    }
    if(!empty($param['wd'])){
        $param['wd'] = htmlspecialchars(urldecode($param['wd']));
        $where['user_name'] = ['like','%'.$param['wd'].'%'];
    }

    //時間判斷條件
    if(!empty($param['start_time'])){
        $where['user_last_login_time'] = ['EGT',strtotime($param['start_time'])];
    }
    if(!empty($param['end_time'])){
        $where['user_last_login_time'] = ['ELT',strtotime($param['end_time'])];
    }
    if(!empty($param['start_time']) && !empty($param['end_time'])){
        $where['user_last_login_time'] = [
            ['EGT', strtotime($param['start_time'])],
            ['ELT', strtotime($param['end_time'])],
        ];
    }

    $order='user_id desc';
    $res = model('User')->listData($where,$order,$param['page'],$param['limit']);
    return $res;
}

2、如果不使用Ajax請求：

封裝Excel導出(我封裝到common.php)，代碼如下：

/**
 * 數據導出
 * @param array $title   標題行名稱
 * @param array $data   導出數據
 * @param string $fileName 文件名
 * @param string $savePath 保存路徑
 * @param $type   是否下載  false--保存   true--下載
 * @return string   返回文件全路徑
 */
function exportExcel($title=array(), $data=array(), $fileName='',$sheet='', $savePath='./', $isDown=false){
//    Loader::import('PHPExcel.PHPExcel');
//    Loader::import('PHPExcel.PHPExcel.IOFactory');
    vendor("PHPExcel.PHPExcel");
    vendor("PHPExcel.PHPExcel.IOFactory");
    $obj = new \PHPExcel();

    //橫向單元格標識
    $cellName = array('A', 'B', 'C', 'D', 'E', 'F', 'G', 'H', 'I', 'J', 'K', 'L', 'M', 'N', 'O', 'P', 'Q', 'R', 'S', 'T', 'U', 'V', 'W', 'X', 'Y', 'Z', 'AA', 'AB', 'AC', 'AD', 'AE', 'AF', 'AG', 'AH', 'AI', 'AJ', 'AK', 'AL', 'AM', 'AN', 'AO', 'AP', 'AQ', 'AR', 'AS', 'AT', 'AU', 'AV', 'AW', 'AX', 'AY', 'AZ');

    $obj->getActiveSheet(0)->setTitle($sheet);   //設置sheet名稱
    $_row = 1;   //設置縱向單元格標識
    if($title){
        $_cnt = count($title);
        // $obj->getActiveSheet(0)->mergeCells('A'.$_row.':'.$cellName[$_cnt-1].$_row);   //合併單元格
        // $obj->setActiveSheetIndex(0)->setCellValue('A'.$_row, '數據導出：'.date('Y-m-d H:i:s'));  //設置合併後的單元格內容
        // $_row++;
        $i = 0;
        foreach($title AS $v){   //設置列標題
            $obj->setActiveSheetIndex(0)->setCellValue($cellName[$i].$_row, $v);
            $i++;
        }
        $_row++;
    }

    //填寫數據
    if($data){
        $i = 0;
        foreach($data AS $_v){
            $j = 0;
            foreach($_v AS $_cell){
                $obj->getActiveSheet(0)->setCellValue($cellName[$j] . ($i+$_row), $_cell);
                $j++;
            }
            $i++;
        }
    }

    //文件名處理
    if(!$fileName){
        $fileName = uniqid(time(),true);
    }

    $objWrite = \PHPExcel_IOFactory::createWriter($obj, 'Excel2007');


    if($isDown){   //網頁下載
        header('pragma:public');
        header("Content-Disposition:attachment;filename=$fileName.xls");
        $objWrite->save('php://output');exit;
    }

    $_fileName = iconv("utf-8", "gb2312", $fileName);   //轉碼
    $_savePath = $savePath.$_fileName.'.xlsx';
    $objWrite->save($_savePath);

    return $savePath.$fileName.'.xlsx';
}

    }
    Loader::import('PHPExcel.PHPExcel');
    $objRead = new \PHPExcel_Reader_Excel2007();   //建立reader對象
    if(!$objRead->canRead($file)){
        $objRead = new \PHPExcel_Reader_Excel5();
        if(!$objRead->canRead($file)){
            die('No Excel!');
        }
    }

    $cellName = array('A', 'B', 'C', 'D', 'E', 'F', 'G', 'H', 'I', 'J', 'K', 'L', 'M', 'N', 'O', 'P', 'Q', 'R', 'S', 'T', 'U', 'V', 'W', 'X', 'Y', 'Z', 'AA', 'AB', 'AC', 'AD', 'AE', 'AF', 'AG', 'AH', 'AI', 'AJ', 'AK', 'AL', 'AM', 'AN', 'AO', 'AP', 'AQ', 'AR', 'AS', 'AT', 'AU', 'AV', 'AW', 'AX', 'AY', 'AZ');

    }
    return $data;
}
