我需要将 doc 文件转换为 pdf 格式,因为我正在遵循下面提到的 saaspose 函数(http://api.saaspose.com/v1.0/words/help)我没有收到错误,并且上传了垃圾文件使用 doc 文件,但我需要上传具有相同 doc 内容的 pdf 文件。
private function convertDocToPdf($inputFileName,$outputFileName)
{
$doc = new WordDocument("");//Word document is a class to create new document
$result = $doc->ConvertLocalFile($inputFileName, $outputFileName,"pdf");
