POCorrupted ZipArchive after setContent() in php symfony
text
Body
copied!<p>I have a real strange behavior when sending a zip archive containing a any type of file in symfony. The problem is that the zip file, that I download from the browser contains an extra 'bit' at the beginning of the file.</p> <p>Here's my code:</p> <pre><code>$tmpFileName = tempnam("/tmp", "xb_"); $zip = new ZipArchive(); $zip->open($tmpFileName, ZipArchive::CREATE); $zip->addFile('[directory_inside_webspace]/test.pdf', 'myTest.pdf'); $zip->close(); $this->getResponse()->clearHttpHeaders(); $this->getResponse()->setContent(file_get_contents($tmpFileName)); $this->getResponse()->setHttpHeader('Content-Type', 'application/zip'); $this->getResponse()->setHttpHeader('Content-Disposition', 'attachment; filename=archive.zip'); return sfView::NONE; </code></pre> <p>Now here's what is strange. The temporary zip file under /tmp is fine. I can extract it without any problems. But the file the browser sends to me is corrupt. When I open both of them in hex editor, the first few bytes look like:</p> <pre><code>working file: 50 4B 03 04 14 00 00 corrupt file: 0A 50 4B 03 04 14 00 00 </code></pre> <p>When I remove the addition '0A' from the corrupt file I can open it without problems. It's now the exactly same file as the tmp file created in /tmp.</p> <p>Did anyone had a behavior like this before?? I'm stucked at this problem for over 4 days now and I'm not able to find the error. I use exactly the same code in another symfony module and it's working in there. Any ideas ?</p> <p>-----Update------</p> <p>The problem wasn't related to the zipArchive or setContent. I had a query at the beginning of the function.</p> <pre><code>$bill = Doctrine::getTable('Bill')->find($request->getParameter('id')); </code></pre> <p>In the class 'Bill.class.php' in my doctrine model I had a blank line before </p> <pre><code><?php </code></pre> <p>So when the class Bill was instantiated the new line was print to screen.</p> <p>I just wonder why php doesn't give an error message like 'headers already send' when sending the zip Archive to the browser.</p>

Querying!
