基於ThinkPHP開發的PHPExcel導出

首先咱們須要去PHPExcel官網下載開源包

下載好了之後只須要把裏面的classes文件夾解壓出來就能夠用了！

固然，在處理的數據量龐大的時候就會報錯，提示你看nginx日誌什麼的，這個時候你須要檢查php.ini中的memory_limit，若是是128什麼的比較小的數字就改大一點，改爲512，就能夠解決了~

在ThinkPHP中，文件的命名空間仍是很重要的，我試着按照其餘的第三方命名寫namespace可是仍是不行，最後我是這麼作的

第一步：重命名classes爲Excel，而且將文件夾內的PHPExcel.php重命名成PHPExcel.class.php

而後放入到目錄文件

 

 

而後在控制層導入，直接use的話是會報錯找不到類文件的。。。也許是內核裏面的路由問題，因而我是在實例化的時候寫的詳細地址竟然能夠出來了

$objPHPExcel = new \Org\Excel\PHPExcel();   就是這樣

可是這樣類文件的一些方法是不能夠用的，若是調用須要在方法前面加一個\

好比這樣：

$objSheet->getStyle("A1:Z1")->getFill()->setFillType(\PHPExcel_Style_Fill::FILL_SOLID)->getStartColor()->setARGB('#00FF00');//給單元格填充背景顏色

以下是具體代碼：

//excel導出
public function excel(){

    //查詢sql生成數組
    $loan = M("loan");
    $data = $loan->select();

    $objPHPExcel = new \Org\Excel\PHPExcel();//實例化類文件 等同於在桌面新建一個excel表格
    $objSheet = $objPHPExcel->getActiveSheet();//得到當前活動sheet操做對象
    $objSheet->setTitle('loan_info');//給當前活動sheet修更名稱

    $objSheet->getDefaultStyle()->getAlignment()->setVertical(\PHPExcel_Style_Alignment::VERTICAL_CENTER)->setHorizontal(\PHPExcel_Style_Alignment::HORIZONTAL_CENTER);//設置單元格垂直居中、水平居中
    $objSheet->getStyle("A1:Z1")->getFont()->setName("微軟雅黑")->setSize(10)->setBold(true);//設置單元格範圍的字體、字體大小、加粗
    $objSheet->getStyle("A1:Z1")->getFill()->setFillType(\PHPExcel_Style_Fill::FILL_SOLID)->getStartColor()->setARGB('#00FF00');//給單元格填充背景顏色

    //添加邊框
    $styleArray = array(
        'borders' => array(
            'outline' => array(
                'style' => \PHPExcel_Style_Border::BORDER_THICK,
                'color' => array('argb' => '#F0F8FF'),
            ),
        ),
    );
    $objSheet->getStyle("A1")->applyFromArray($styleArray);
    $objSheet->getStyle("B1")->applyFromArray($styleArray);
    $objSheet->getStyle("C1")->applyFromArray($styleArray);

    $objSheet->getStyle("W1")->applyFromArray($styleArray);



    $objSheet->setCellValue("A1","ID")
