If Possible to Read existing PDF content position and add the some content after over the existing content in laravel?

Question

Laravel Package: "setasign/fpdi": "^2.3", "setasign/fpdf": "^1.8"

$pdf = new \setasign\Fpdi\Fpdi('L','mm','A4');
$pageCount = $pdf->setSourceFile(public_path().'/'.$url);
$pdf->setFont('Arial', 'B', 10);
for($i = 1; $i <= $pageCount; $i++){
    $tplIdx = $pdf->importPage($i);
    $pageDimensions = $pdf->getImportedPageSize($tplIdx);
    $pdf->addPage($pageDimensions['orientation'], $pageDimensions);
    $pdf->useTemplate($tplIdx);
 }

If It Possible read the content of the last page and get after page content ordinate of the current position. then Write new content without add new page or whitespaces

But in this code pageCount is work properly, Just need the last line position and then after write new content — Mdr Kuchhadiya, Nov 09 '20 at 10:18
"last line position" is (if I understand correct) an information resolved by rendering the text of the imported page. That's not supported by FPDI. — Jan Slabon, Nov 09 '20 at 10:45
@JanSlabon you have an idea of a supported PHP library? so please tell me — Mdr Kuchhadiya, Nov 09 '20 at 11:01
Nothing related to FPDI. But in combination with our [SetaPDF-Extractor](https://setasign.com/extractor) (not free!) there may be a solution. — Jan Slabon, Nov 09 '20 at 11:25

If Pdf Generate using DomPdf so you can generate HTML file using

$pdf->getDomPDF()->outputHtml()

Generated html file using DomPDF add some element like this:

<div id="divId"></div>

Then whenever you need to edit this document, you need to read the HTML file line by line and Edit document:

$url=public_path() .'/test.html';
$htmlFile='';
foreach(file($url) as  $key => $line){
  if(strpos($line, 'id="divId"') !== false){
    $line='<div>Hello world</div>';
  }
  $htmlFile.=$line;
}
$pdf = PDF::loadHTML($htmlFile)->setPaper('a4', 'landscape');
$pdf->output();
