PHP FileInterface::getType方法代码示例

 /**
  * This method actually does the processing of files locally
  *
  * takes the original file (on remote storages this will be fetched from the remote server)
  * does the IM magic on the local server by creating a temporary typo3temp/ file
  * copies the typo3temp/ file to the processingfolder of the target storage
  * removes the typo3temp/ file
  *
  * @param \TYPO3\CMS\Core\Resource\ProcessedFile $processedFile
  * @param \TYPO3\CMS\Core\Resource\FileInterface $file
  * @param array $configuration
