我有一个流文档，我需要将其转换为 PDF 。
想法是将其流保存为 PDF
我的代码：
$responce = $this->getDocumentContent();//this function returns me the $responce content bellow.
$documentFolder = $this->getDirectory().'/document/'; //var/www/project/document/
$documentFullPath = $this->getDirectory().'/document/file1.pdf';
$this->_io->mkdir($documentFolder, 0775);//create folder var/www/project/document
$document = fopen($documentFullPath, "w+");//create pdf file var/www/project/document/file1.pdf
fwrite($document, $responce);
fclose($document);
现在使用此代码，我在file1.pdf中很好地创建了var/www/project/document/file1.pdf，但是它是空的！，没有内容，file1.pdf的权重不是0而是{ {1}}，但我什么都看不到。我不知道问题出在哪里。
