Answer 1

Assuming that the original pdf is having 5 pages (known as fivepage.pdf), then you may use the following steps to remove page 3 from it and generate a new pdf known as combined.pdf
use Imagick to open the pdf
determine the number of pages
loop over each page of this pdf
save the pages into separate , temporary jpeg files
push the jpeg files (except page 3, $i==2) into array
use the array to generate the "combined.pdf"
delete all the temp jpeg files
So the code is:
<?php
$file="./fivepage.pdf";
$im = new Imagick($file);
$resultimages = array();
$noOfPagesInPDF = $im->getNumberImages();
// loop over all the pdf pages
for ($i = 0; $i < $noOfPagesInPDF; $i++) {
$url = $file.'['.$i.']';
$image = new Imagick();
// $image->setResolution(300,300);
// use the above line if you want higher resolution
$image->readimage($url);
$image->setImageFormat("jpg");
$image->writeImage("./temp_".($i+1).'.jpg');
// include all pages except page 3 ($i==2)
if ($i!=2) {
array_push($resultimages, "./temp_".($i+1).'.jpg');
}
}
// generate the resulting pdf (omitting page 3)
$pdf = new Imagick($resultimages);
$pdf->setImageFormat('pdf');
$pdf->writeImages('combined.pdf', true);
// clear temp images
for ($i = 0; $i < $noOfPagesInPDF; $i++) {
unlink("./temp_".($i+1).'.jpg');
}
echo "pdf without page 3 saved";
?>
