PHPExcel未正确写入文件

我的网站允许用户上传

.xls

、

.xlsx

和

.csv

文件。如果文件不是

.csv

，它将转换为一个文件并保存到服务器。问题是我的代码没有保存文件。相反，它只保存一个空白单元格。我的代码有什么问题，如何编辑它以使其完成我寻求的任务

require_once('Classes/PHPExcel/IOFactory.php'); 
require_once("mcl_Oci.php");
$filename = $_FILES['uploaded']['name'];
$ext = pathinfo($filename, PATHINFO_EXTENSION);

    if ($_FILES['uploaded']['error'] !== UPLOAD_ERR_OK) {
        die("Upload failed with error code #" . $_FILES['uploaded']['error']);
    }

    if($ext == 'xls') {

        $inputFileType = 'Excel5';
        $inputFileName = $_FILES['uploaded']['tmp_name'];
        $objReader = PHPExcel_IOFactory::createReader($inputFileType);
        $objPHPExcelReader = $objReader->load($inputFileName);
        $loadedSheetNames = $objPHPExcelReader->getSheetNames();

        $objWriter = PHPExcel_IOFactory::createWriter($objPHPExcelReader, 'CSV');

            $objWriter->setSheetIndex($sheetIndex);
            $objWriter->save('abc.csv'); //THIS IS WHERE IT ERRORS//


        $files = fopen('abc.csv', 'r'); 

            while (($line = fgetcsv($files)) !== FALSE) {
                $csv_array[] = array_combine(range(1, count($line)), array_values($line));
        }       
        echo 'Your .xls file was uploaded successfully. Have a nice day.';


    } elseif($ext == 'csv'){
        $inputFileType = 'CSV';
        $inputFileName = $_FILES['uploaded']['tmp_name'];
        $objReader = PHPExcel_IOFactory::createReader($inputFileType);
        $objPHPExcelReader = $objReader->load($inputFileName);
        $loadedSheetNames = $objPHPExcelReader->getSheetNames();
        $objWriter = PHPExcel_IOFactory::createWriter($objPHPExcelReader, 'CSV');

            $objWriter->save('abc.csv');

        $files = fopen('abc.csv', 'r');
        while (($line = fgetcsv($files)) !== FALSE) {
                $csv_array[] = array_combine(range(1, count($line)), array_values($line));
        }   
        echo 'Your .csv file was uploaded successfully. Have a nice day.';

    } elseif($ext == 'xlsx') {
        $inputFileType = 'Excel2007';

        $inputFileName = $_FILES['uploaded']['tmp_name'];

        $objReader = PHPExcel_IOFactory::createReader($inputFileType);
        $objPHPExcelReader = $objReader->load($inputFileName);

        $loadedSheetNames = $objPHPExcelReader->getSheetNames();

        $objWriter = PHPExcel_IOFactory::createWriter($objPHPExcelReader, 'CSV');

        $objWriter->save(str_replace('.xlsx', '.csv', $inputFileName));

            $objWriter->save('abc.csv');

        $files = fopen('abc.csv', 'r');

        while (($line = fgetcsv($files)) !== FALSE) {
                $csv_array[] = array_combine(range(1, count($line)), array_values($line));
        }   
        echo 'Your .xlsx file was uploaded successfully. Have a nice day.';     
    }

    else {
        echo "This is not an accepted file type. Please save as either '*.csv' or '*.xls' and re-upload.";
    }       

更新

我的代码完全适用于

.csv

文件。但是，它不适用于

.xls

或

.xlsx

此

if($ext='xls') {

正在进行分配，使所有文件成为

xls

。应该是

if($ext == 'xls') {
        ^^---note the doubled "=" signs.

在所有

if（）

测试中，都会出现完全相同的错误

同样，您似乎从来没有检查文件上传是否成功，这是一件非常糟糕的事情。永远不要假设成功。始终假定失败，并将成功视为惊喜：

if ($_FILES['uploaded']['error'] !== UPLOAD_ERR_OK) {
   die("Upload failed with error code #" . $_FILES['uploaded']['error']);
}

---

这是最终允许我上传单张

.xlsx

、

.xls

和

.csv

文件的代码。上传后，如OP中所述，我将任何

.xlsx

或

.xls

转换为

.csv

，并将其保存到目录中

    require_once('Classes/PHPExcel/IOFactory.php'); 
    require_once("mcl_Oci.php");
    $filename = $_FILES['uploaded']['name'];
    $ext = pathinfo($filename, PATHINFO_EXTENSION);

    if ($_FILES['uploaded']['error'] !== UPLOAD_ERR_OK) {
        die("Upload failed with error code #" . $_FILES['uploaded']['error']);
    }

    if($ext == 'xls') {

        $inputFileType = 'Excel5';
        $inputFileName = $_FILES['uploaded']['tmp_name'];
        $objReader = PHPExcel_IOFactory::createReader($inputFileType);
        $objPHPExcelReader = $objReader->load($inputFileName);
        $loadedSheetNames = $objPHPExcelReader->getSheetNames();

        $objWriter = PHPExcel_IOFactory::createWriter($objPHPExcelReader, 'CSV');



        $objWriter->save(str_replace('.xls', '.csv', $inputFileName));

            $objWriter->save('abc.csv');


        $files = fopen('abc.csv', 'r'); 

            while (($line = fgetcsv($files)) !== FALSE) {
                $csv_array[] = array_combine(range(1, count($line)), array_values($line));
        }       
        echo 'Your .xls file was uploaded successfully. Have a nice day.';


    } elseif($ext == 'csv'){
        $inputFileType = 'CSV';
        $inputFileName = $_FILES['uploaded']['tmp_name'];
        $objReader = PHPExcel_IOFactory::createReader($inputFileType);
        $objPHPExcelReader = $objReader->load($inputFileName);
        $loadedSheetNames = $objPHPExcelReader->getSheetNames();
        $objWriter = PHPExcel_IOFactory::createWriter($objPHPExcelReader, 'CSV');

            $objWriter->save('abc.csv');

        $files = fopen('abc.csv', 'r');
        while (($line = fgetcsv($files)) !== FALSE) {
                $csv_array[] = array_combine(range(1, count($line)), array_values($line));
        }   
        echo 'Your .csv file was uploaded successfully. Have a nice day.';

    } elseif($ext == 'xlsx') {
        $inputFileType = 'Excel2007';

        $inputFileName = $_FILES['uploaded']['tmp_name'];

        $objReader = PHPExcel_IOFactory::createReader($inputFileType);
        $objPHPExcelReader = $objReader->load($inputFileName);

        $loadedSheetNames = $objPHPExcelReader->getSheetNames();

        $objWriter = PHPExcel_IOFactory::createWriter($objPHPExcelReader, 'CSV');

        $objWriter->save(str_replace('.xlsx', '.csv', $inputFileName));

            $objWriter->save('abc.csv');

        $files = fopen('abc.csv', 'r');

        while (($line = fgetcsv($files)) !== FALSE) {
                $csv_array[] = array_combine(range(1, count($line)), array_values($line));
        }   
        echo 'Your .xlsx file was uploaded successfully. Have a nice day.';     
    }

    else {
        echo "This is not an accepted file type. Please save as either '*.csv' or '*.xls' and re-upload.";
    }

然而，问题仍然存在。谢谢你！你看到其他问题了吗？很难说。你似乎在练习“随机缩进”学派的代码格式，所以你的代码很难理解。哈哈，不，我使用的FTP不容易复制/粘贴代码xD。我将使用JSFIDLE清理并重新更新代码哈哈！SorryUpdated，我还添加了错误消息-似乎没有任何作用。您的csv

fopen（）

在xls部分中，因此如果您正在处理csv，

$files

永远不会被设置，您的fgetcsv将失败并返回布尔值false。不要假设带有

.xls

的文件是Excel文件，它很可能是一个csv或html文件，只是被赋予了扩展名.xls。。。。使用

PHPExcel\u IOFactory:：identify（）

找出文件类型的真正含义，并基于此创建读取器，而不是假设上传者“做对了”。好的，在我的网站的这一部分最终发布之前，我肯定会根据这些信息进行更新。但是，鉴于我正在从Microsoft Excel创建

.xls

，这是否意味着无论发生什么情况，该文件都是正确的？因此，它不应该是错误的。您在$loadedSheetNames中的循环正在为每个工作表保存到同一个csv文件中（即使集合中的最后一个工作表为空）^^当我删除$loadedSheetNames部分时，它的工作方式是预期的！非常感谢你，马克·贝克。现在只有错误

致命错误：对
.xls
文件的第128行中的非对象调用成员函数getHighestDataColumn（），很难简单地说“停止运行您需要工作的基本功能”并期望工作正常：有点像从车中取出发动机，因为它会发出噪音，但仍然期待着这辆车能开。。。。如果没有更多的细节，我无法解决这个问题，也许堆栈转储或类似的方法可能会有所帮助。。。。至少，我需要知道您的代码在错误发生时正在做什么
