笨与PHPExcel严重错误就不能重新声明类IOFactory(CodeIgniter with P

我试图用PHPExcel使用CodeIgniter。

我的问题是，当我想下面使用这种方法，我得到了PHP的致命错误：不能重新声明类IOFactory

如果你不确定的文件类型，你可以使用IO厂的标识（）方法来确定你需要的读者，使用createReader（）方法来实例化对象读者面前。

下面是我的代码：

$this->load->library('PHPExcel');

$this->load->library('PHPExcel/IOFactory');

$path = $upload_data['full_path'];

$inputFileType = PHPExcel_IOFactory::identify($path);

$objReader = PHPExcel_IOFactory::createReader($inputFileType);

$objPHPExcel = $objReader->load($path);

$objWorksheet = $objPHPExcel->getActiveSheet();

我试图找到如果IOFactory类已经在某处所创建，但无法找到它。

仅供参考，即时通讯使用的是最新版本的CodeIgniter（2.1）和PHPExcel（1.7.6）在这个时候写的。

Answer 1:

没有必要写

$this->load->library('PHPExcel');

只是开始

$this->load->library('PHPExcel/IOFactory');

编辑:::

在项目中，我通过这些方式来完成，

第一步：在libraries\PHPExcel\Reader

重命名Excel5.php到PHPExcel_Reader_Excel5.php

第2步：

$filePath = $dir.$uploadedfile;
$objReader = $this->load->library('PHPExcel/Reader/PHPExcel_Reader_Excel5', $filePath);
$objReader = new PHPExcel_Reader_Excel5();
$objPHPExcel = $objReader->load($filePath);     
$rowIterator = $objPHPExcel->getActiveSheet()->getRowIterator();                        
$sheet = $objPHPExcel->getActiveSheet();
$maxRowIndex = $sheet->getHighestRow();
$highestColumn = $sheet->getHighestColumn();
$maxColIndex = PHPExcel_Cell::columnIndexFromString($highestColumn);

我使用PHPExcel与CI和grocery_CRUD上传数据从Excel在MySQL。这是我的方式：

//我的Excel的CI库

<?php

if (!defined('BASEPATH'))     exit('No direct script access allowed');
require_once APPPATH . "/third_party/PHPExcel/IOFactory.php";
/*
 * PHPExcel Lib For CI
 *
 * Class Excel

class Lib_excel extends PHPExcel_IOFactory {
    public function __construct() {
    }
}
?>

//我的Excel CI模式

<?php
// My CI Model for handling all Excel methods
if (!defined('BASEPATH'))     exit('No direct script access allowed');
// Class Model extend with CI Model
class Mod_excel extends CI_Model {
    function __construct() {
        // Call the Model constructor
        parent::__construct();
    }
    /**
     * Read data from Excel file
     * 

     * @input string $excelFileName
     * @input string $columnName (starting column point)
     * @input string $startRow (starting column point)
     * @return array $cellValues
     *
     * @example code
     *  $excelFileName = $_FILES['uploadedfile']['tmp_name'];
     *  $columnName = 'B';
     *  $startRow = '2';
     *  $cellValues = readWithExcel($excelFileName, $columnName, $startRow);
     *  $iterator = new RecursiveIteratorIterator(new RecursiveArrayIterator($cellValues));
     *  foreach($iterator as $value) {
     *      $insert_data[] = $value;
     *  }
     */
    function readWithExcel($excelFileName, $columnName, $startRow) {
        //load our new Lib Excel library as object excel
        $this->load->library('Lib_excel', null, 'excel');
        // load excel file
        $objPHPExcel  = $this->excel->load($excelFileName);
        // get active sheets
        $objWorksheet = $objPHPExcel->getActiveSheet();
        // get highest row column
        $lastRow      = $objWorksheet->getHighestRow();
        // check cell value empty or not
        for ($i = $startRow; $i < $lastRow; $i++) {
            $colB = $objPHPExcel->getActiveSheet()->getCell($columnName . $i)->getValue();
            if ($colB == NULL || $colB == '') {
                die('The Cell' . ' <strong>B' . $i . '</strong> is empty. Please, remove or fill with data');
            }
        }
        // get excel data with range e.g. (B2:B56)
        $cellValues = $objPHPExcel->getActiveSheet()->rangeToArray("$columnName$startRow:$columnName$lastRow");
        // return all data as array
        return $cellValues;
    }
}
?>

//我的控制器调用方法

//我的文件夹，我把PHPExcel库在CI

你可以试试这一个，它为我工作：

$filePath = "uploads/import/test.xlx";                                  
$this->load->library('PHPExcel');                         
$objReader = new PHPExcel_Reader_Excel5();                        
$objPHPExcel = $objReader->load($filePath);
$sheetData = $objPHPExcel->getActiveSheet()->toArray(null,true,true,true);
