我有一个陌生人文件，但我不知道它是哪个扩展名，因此我需要将其转换为 PDF ，因此我们的想法是内容，然后我们将其另存为 PDF

I have a stranger document that I don't know which extension it is, and I need to convert it into a PDF, so the idea is to get that content dynamically, then we save it in server as a PDF

我的尝试:

$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);

现在有了这段代码，我在var/www/project/document/file1.pdf中很好地创建了file1.pdf，但是它是空的！，没有内容，file1.pdf的权重不是0而是163.2 Ko，但是我什么都看不到.我不知道问题出在哪里.

Now with this code, I create well the file1.pdf in var/www/project/document/file1.pdf but it is empty !, there is no content, the file1.pdf weight is not 0 but 163.2 Ko but I see anything. I don't know where is the issue.

$responce =

推荐答案

PDF实际上提到了它:

The PDF mentions it actually:

/Producer ([ClibPDF Library 2.02-r1-2] Windows XP)

ClibPDF对PHP的支持早在很早以前就已经转移到PECL中(使用PHP 5.1).该扩展不是面向对象的，因此这里有一些附加的包装器.

ClibPDF support for PHP was moved into PECL a long time ago (with PHP 5.1). The extension was not object oriented, so here is some additional wrapper around it.

替代方法是 Haru ， PDFlib 或基于PHP的可用库之一.

Alternatives are Haru, PDFlib, or one of the available PHP based libraries.
