Php Remove page from existing pdf file

Question

What is the easiest way to remove one page (ie. the last page) from a local pdf file using php? I have around 100 files, and each one needs to have its last page dropped. Optimally, I want to replace the file with a file of the same name that is just one page shorter.

Answer 1

You can use FPDI

Example:

pdf = new FPDI();
$pageCount = $pdf->setSourceFile('document.pdf');

//  Array of pages to skip -- modify this to fit your needs
$skipPages = [3,15,17,22];

//  Add all pages of source to new document
for( $pageNo=1; $pageNo<=$pageCount; $pageNo++ )
{
    //  Skip undesired pages
    if( in_array($pageNo,$skipPages) )
        continue;

    //  Add page to the document
    $templateID = $pdf->importPage($pageNo);
    $pdf->getTemplateSize($templateID);
    $pdf->addPage();
    $pdf->useTemplate($templateID);
}

$pdf->Output();

You can delete de last page using the array size easily.
