PHPExcel内存错误

Question

我使用 PHPExcel Reader 函数将 excel 文件转换为 HTML table。

我收到此错误：致命错误：内存不足（已分配 1827405824）（已尝试分配 106 字节）

我在 php.ini 文件中将 memory_limit 更改为 2048M..

仍然收到错误..

那么我怎样才能只加载我的 Excel 文件的第一个 sheet，它也许可以解决我的问题？

$excel = glob(''.$test.'\'.$client.'.{xlsx,xls,xlsm,xlsm.ink}',GLOB_BRACE);
$filterSubset = new \PHPExcel_Reader_DefaultReadFilter('A','N');
$objReader = \PHPExcel_IOFactory::createReaderForFile($excel[0]);
$objReader->setReadFilter($filterSubset);

$objPHPExcel = $objReader->load($excel[0]);

## THIS DOESNT WORK ?! ##
$objPHPExcel->setActiveSheetIndex(1);

    $links = $objPHPExcel->getActiveSheet()->getHyperlinkCollection();
    var_dump($links);

    foreach ($links as $link){
        $url = $link->getUrl();
        $url = str_replace('file','mnt', $url);
        $link->setUrl($url);
    }

$writer = \PHPExcel_IOFactory::createWriter($objPHPExcel, "HTML");
$writer->generateStyles();
$writer->generateSheetData();

编辑：

我就是这样做的:

    public function showClientAction($client)
{
    $excel = glob(''.$path'.{xlsx,xls,xlsm,xlsm.ink}', GLOB_BRACE);
    $filterSubset = new \PHPExcel_Reader_DefaultReadFilter('A','N');
    $objReader = \PHPExcel_IOFactory::createReaderForFile($excel[0]);
    $objReader->setReadFilter($filterSubset);

    $worksheetList = $objReader->listWorksheetNames($excel[0]);
    $sheetname = $worksheetList[0];

    /**  Advise the Reader of which WorkSheets we want to load  **/

    $objReader->setLoadSheetsOnly($sheetname);

    $objPHPExcel = $objReader->load($excel[0]);

    var_dump($sheetname);

    $writer = \PHPExcel_IOFactory::createWriter($objPHPExcel, "HTML");
    $writer->generateStyles();
    $writer->generateSheetData();

    return $this->render('MonextPerfclientBundle:Default:testexcel.html.twig', array(
        'excelHtml'=>$writer,
        'stylesExcel'=>$writer,
    ));
}

var_dump($sheetname); 输出很好，效果很好！

但是我怎样才能确保只加载第一个 sheet？

它似乎没有更快的加载.. *请注意我的英语..

So How can i only load the first sheet of my Excel file, it can maybe solve my issue ?

直接来自 PHPExcel Documentation

$inputFileType = 'Excel5'; 
$inputFileName = './sampleData/example1.xls'; 
$sheetname = 'Data Sheet #2'; 

/**  Create a new Reader of the type defined in $inputFileType  **/ 
$objReader = PHPExcel_IOFactory::createReader($inputFileType); 
/**  Advise the Reader of which WorkSheets we want to load  **/ 
$objReader->setLoadSheetsOnly($sheetname); 
/**  Load $inputFileName to a PHPExcel Object  **/ 
$objPHPExcel = $objReader->load($inputFileName);

如果您不知道第一个工作表的名称，那么 PHPExcel 提供了一个 helper method 来获取工作表名称列表而无需加载整个文件。
