PHP Get height and width in Pdf file proprieties

Question

I have a PDF file. I would to get it height and width in mm.

So I do an exec(pdfinfo ... ); I have this result :

Creator: Adobe InDesign CS5 (7.0.3) Producer: Acrobat Distiller 9.4.2 (Macintosh) CreationDate: Mon Jan 30 15:48:43 2012 ModDate: Fri Feb 10 10:35:05 2012 Tagged: no Pages: 34 Encrypted: no Page size: 552.744 x 708.643 pts File size: 80724791 bytes Optimized: yes PDF version: 1.3

I have a script witch extract my info :

<?php 
$output = shell_exec("pdfinfo ".$pdflivrelink);
$data = explode("\n", $output); //puts it into an array
for($c=0; $c < count($data); $c++) {
        if(stristr($data[$c],"Pages") == true) {
        $pagesnumber = trim(substr($data[$c],6));
        }
        if(stristr($data[$c],"Page size") == true) {
            $pagesize_H = height_pdf(trim(substr($data[$c],9)));
        }
        if(stristr($data[$c],"Page size") == true) {
            $pagesize_L = width_pdf(trim(substr($data[$c],9)));
        }

}
function height_pdf($size){
$hauteur = round(substr($size,7,7)/2.83);
return $hauteur;
}
function width_pdf($size){
$largeur = round(substr($size,17,7)/2.83);
return $largeur;
} ?>

It's OK, because I have three numbers dot three numbers (552.744 x 708.643). But, I don't know why, some PDF files have this info :

Creator: pdftk 1.41 - www.pdftk.com Producer: iText 2.1.5 (by lowagie.com) CreationDate: Mon Feb 27 13:18:23 2012 ModDate: Mon Feb 27 16:26:12 2012 Tagged: no Pages: 36 Encrypted: no Page size: 425.2 x 538.582 pts File size: 5097597 bytes Optimized: yes PDF version: 1.6

425.2 x 538.582 : So my script doesn't work!

Can you help me? thank a lot!

I test this :

    $output = shell_exec("pdfinfo ".$pdflivrelink);
    $data = explode("\n", $output); //puts it into an array
    for($c=0; $c < count($data); $c++) {
            if(stristr($data[$c],"Pages") == true) {
            $pagesnumber = trim(substr($data[$c],6));

            }
            if(stristr($data[$c],"Page size") == true) {
                echo $data[$c];
    preg_match('/Page size: ([0-9]*\.?[0-9]?) x ([0-9]*\.?[0-9]?)/', $data[$c], $matchess);
    $width = round($matchess[1]/2.83);
    $height = round($matchess[2]/2.83);

            }
}
echo "width = $width<br>height = $height";

it result :

Page size: 425.2 x 538.582 ptswidth = 0 height = 0

A little regex will get you the correct results.

<?php
$str = 'Creator: pdftk 1.41 - www.pdftk.com Producer: iText 2.1.5 (by lowagie.com) CreationDate: Mon Feb 27 13:18:23 2012 ModDate: Mon Feb 27 16:26:12 2012 Tagged: no Pages: 36 Encrypted: no Page size: 425.2 x 538.582 pts File size: 5097597 bytes Optimized: yes PDF version: 1.6';

preg_match('/Page size: ([0-9]*\.?[0-9]?) x ([0-9]*\.?[0-9]?)/', $str, $matches);
$width = round($matches[1]/2.83);
$height = round($matches[2]/2.83);

echo "width = $width<br>height = $height";
?>

Update ( asked for more details ) : Complete working example below. I've updated Regex to match real output from pdfinfo

<?php

$output = shell_exec("pdfinfo ".$pdflivrelink);

// find page count
preg_match('/Pages:\s+([0-9]+)/', $output, $pagecountmatches);
$pagecount = $pagecountmatches[1];

// find page sizes
preg_match('/Page size:\s+([0-9]{0,5}\.?[0-9]{0,3}) x ([0-9]{0,5}\.?[0-9]{0,3})/', $output, $pagesizematches);
$width = round($pagesizematches[1]/2.83);
$height = round($pagesizematches[2]/2.83);

echo "pagecount = $pagecount <br>width = $width<br>height = $height";

?>

Thanks for your help! I have width = 0 height = 0 – Seb Gy Mar 08 '12 at 18:32
Because you are still doing the `$data = split()` line. If you rant he regex directly on $output, that should be all you need to do. You can get rid of the entire loop if you combine this with the other answer's regex to get page num. – AndrewR Mar 09 '12 at 15:59
Can you more explain your idea? I don't all understand, thanks – Seb Gy Mar 09 '12 at 21:18
@AndrewR Thank you very much for your valuable answer .... would you help me to get px from this dimension ...? – Nadimul De Cj Feb 11 '16 at 04:44

Using Fpdi, noting the use of getTemplateSize it's...

const INCHESTOMM = 25.4;

public static function getPDFdimensions($strFilename): array
{
    $pdf1 = new FPDI('P', 'in');
    $pdf1->setSourceFile($strFilename);
    $tplIdx1 = $pdf1->importPage(1);
    $size = $pdf1->getTemplateSize($tplIdx1);
    $w = $size["width"];
    $h = $size["height"];
    return [round($w * self::INCHESTOMM), round($h * self::INCHESTOMM)];
}

Do it with a preg_match():

// Debugging:
$output = shell_exec("pdfinfo ".$pdflivrelink);
var_dump($output);

// Dimension:
preg_match('~ Page size: ([0-9\.]+) x ([0-9\.]+) pts ~', $output, $matches);
var_dump($matches);


// No of pages:
preg_match('~ Pages ([0-9]+) ~', $output, $matches);
var_dump($matches);

Thanks for your help! I have array(0) { } – Seb Gy Mar 08 '12 at 18:32
Not good. `$output` is `$output = shell_exec("pdfinfo ".$pdflivrelink);` ? – powtac Mar 08 '12 at 18:34
yes, when I do $output = shell_exec("pdfinfo ".$pdflivrelink); I haven't result, but when I do $output ="the text..." it's result : array(3) { [0]=> string(32) " Page size: 425.2 x 538.582 pts " [1]=> string(5) "425.2" [2]=> string(7) "538.582" } – Seb Gy Mar 08 '12 at 18:38
I do this : preg_match('~ Page size: ([0-9\.]+) x ([0-9\.]+) pts ~', shell_exec("pdfinfo ".$pdflivrelink), $matches); var_dump($matches); same result : array(0) { } – Seb Gy Mar 08 '12 at 18:40
Try the "No of pages:" pattern. – powtac Mar 08 '12 at 18:53
Does it work when you use this `$output = 'Creator: pdftk 1.41 - www.pdftk.com Producer: iText 2.1.5 (by lowagie.com) CreationDate: Mon Feb 27 13:18:23 2012 ModDate: Mon Feb 27 16:26:12 2012 Tagged: no Pages: 36 Encrypted: no Page size: 425.2 x 538.582 pts File size: 5097597 bytes Optimized: yes PDF version: 1.6';` – powtac Mar 08 '12 at 18:57
Then there is something wrong with `shell_exec("pdfinfo ".$pdflivrelink)` – powtac Mar 09 '12 at 12:05
I also deducting that. How shall we do it ? – Seb Gy Mar 09 '12 at 12:53
It give me : string(352) "Title: unknown Creator: Adobe InDesign CS5.5 (7.5) Producer: Adobe PDF Library 9.9 CreationDate: Tue Jan 31 17:05:25 2012 ModDate: Fri Feb 10 10:42:57 2012 Tagged: yes Pages: 34 Encrypted: no Page size: 581.108 x 793.7 pts File size: 31374145 bytes Optimized: yes PDF version: 1.3 " (It's about a new PDF file don't worry) – Seb Gy Mar 09 '12 at 14:39

Why not use plain PHP to get the pdf dimensions?

<?php
function get_pdf_dimensions($path, $box="MediaBox") {
    //$box can be set to BleedBox, CropBox or MediaBox 

    $stream = new SplFileObject($path); 

    $result = false;

    while (!$stream->eof()) {
        if (preg_match("/".$box."\[[0-9]{1,}.[0-9]{1,} [0-9]{1,}.[0-9]{1,} ([0-9]{1,}.[0-9]{1,}) ([0-9]{1,}.[0-9]{1,})\]/", $stream->fgets(), $matches)) {
            $result["width"] = $matches[1];
            $result["height"] = $matches[2]; 
            break;
        }
    }

    $stream = null;

    return $result;
}

var_dump(get_pdf_dimensions("file.pdf"));

@NadimulDeCj use $box="BleedBox" to get width and height. – naf4me Feb 11 '16 at 08:14
@MAH ... Thank you ... i got width and height ... but i also need page number of pdf .... – Nadimul De Cj Feb 11 '16 at 08:17
Please use this code to get if(class_exists('Imagick')){ $image = new Imagick(); $image->pingImage($pdf_file); echo $image->getNumberImages(); } – naf4me Feb 11 '16 at 10:34

Imagick library can be used to get the dimensions of file

 $image = new Imagick($file);
 $geo=$image->getImageGeometry();
 $width=$geo['width'];
 $height=$geo['height'];

If imagick library is not installed, Ubuntu users can use the following command to install it:

 sudo apt-get install php-imagick
 php -m | grep imagick
 sudo service apache2 restart

Since you know the format of the size string, you can also do it like below. (This function returns width and height in an array.)

function size_pdf($size){
    $result = array();
    $tmp = exlode('x', $size);
    $result['height'] = round(trim($tmp[0])/2.83);
    $result['width'] = round(trim($tmp[1])/2.83);

    return $result;
}
