FPDI merge PDF files, strange line appears

Question

I have to merge PDF files when a user needs to. The files are already existing and everything is fine. I'm using the fallowing code to merge the files: ``` class concat_pdf extends FPDI { var $files = array(); function setFiles($files) { $this->files = $files; } function concat() { foreach($this->files AS $file) { $pagecount = $this->setSourceFile($file); for($i = 1; $i <= $pagecount; $i++) { $this->AddPage('P'); $tplidx = $this->ImportPage($i); $this->useTemplate($tplidx); } } } } $pdf = new concat_pdf(); $pdf->setFiles($files); //$files is an array with existing PDF files. $pdf->concat(); $pdf->Output("bulk.pdf", "D"); ``` All files are merged and all the content is there. The problem is, at the top of each page in the new file, a black line appears. The contents, margins, etc. are all absolutely the same as the original file, but this line comes out of nowhere (that I can tell). It is not thick, but is clearly visible. It doesn't mess with the other content or anything, but is not…

Accepted Answer

A better thing to do as you won't have to modify the source is to add the lines:

```
    $this->setPrintHeader(false);
    $this->setPrintFooter(false);
```

at the beginning of your concat() function.
