如何在slim 3中使用fopen()fwrite()创建一个文件

问题描述 投票:-1回答:1

我有一个应用程序,我上传一个xml文件,然后它被转换为json,其中使用fopen(),fwrite()php函数在控制器内创建json文件。我的问题是我在制作json文件时遇到问题。我不知道是什么问题,但相同的代码运行在基本的PHP,它不适用于slim 3框架。

示例代码如下:

$files = $request->getUploadedFiles();

if (empty($files['file'])) {
    throw new Exception('Expected a file');
}

$file    = $files['file'];
$getFile = $file->getClientFilename();        

$extension = pathinfo($file->getClientFilename(), PATHINFO_EXTENSION);
//check file extension
if($extension != 'xml') {
    $uploadOk = 0;
    $error .= 'Not the correct file type';
} else {
    $path = $file->moveTo( __DIR__ . '/../../../public/Backup/' . $getFile);

    if($path) {
        $XMLFilePath = __DIR__ . '/../../../public/Backup/' . $getFile;

        //convert xml to json
        $fileContents = file_get_contents($XMLFilePath);
        $fileContents = str_replace(array("\n", "\r", "\t"), '', $fileContents);
        $fileContents = trim(str_replace('"', "'", $fileContents));
        $simpleXml    = simplexml_load_string($fileContents);

        $json      = json_encode($simpleXml);
        $file_name = pathinfo($file->getClientFilename(), PATHINFO_FILENAME);

        $filename = preg_replace('/\\.[^.\\s]{3,4}$/', '', $file_name);
        $filename = str_replace(' ', '_', $filename);
        $filename = str_replace('.xml', '', $filename);

        $jsonFileName = $filename . '_' . str_replace(":", "_", $dateTime); 
        //join time and file name to create unique file name
        $jsonFile = __DIR__ . '/../public/' . $jsonFileName . ".json";

       //create json file
       $jsonWrite = fopen($jsonFile, "w+");

       if(fwrite($jsonWrite, $json)) {
           $success .= 'File parsed from xml to json';

           return $response->withJson($success, 200);
           fclose($jsonWrite);
       } else {
           // failed to write to json file
           $error .= 'failed to write to json file';

           return $response->withJson($error, 200);
       }
...

$ file_name从上传的xml文件中获取其getClientFilename()。所以假设我上传了“exam_results.xml”,$ file_name只会获得exam_results。

那么我怎样才能使这段代码有效呢?或者如果有其他方式可以请帮助

您没有关闭该文件

if(fwrite($jsonWrite, $json)) {
    $success .= 'File parsed from xml to json';

    return $response->withJson($success, 200);   // return ?
    fclose($jsonWrite);                          // this line never get called!!!
} else {

返回前移动fclose
