问题
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
My try :
$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);
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 =
string(163146) "%PDF-1.4

回答1:
The PDF mentions it actually:
/Producer ([ClibPDF Library 2.02-r1-2] Windows XP)
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.
Alternatives are Haru, PDFlib, or one of the available PHP based libraries.
