如何通过PHP或imagemagick检测多页PDF？

问题描述：

For instance, when I uploaded a file to the temp folder on server, are there any way to scan through the folder and check whether a specific file is multi page or not?

Some code like:

$files = scandir ('$tempSrc');
foreach ($files as $pdf) {
    $isMulti = //exec some command or call php function (if any?);
    echo $isMulti;
}

例如，当我将文件上传到服务器上的temp文件夹时，有没有办法扫描文件夹并检查特定文件是否是多页？ p>

一些代码如： p>

  $ files = scandir（'$ tempSrc'  ）; 
 
Nachach（$ files as $ pdf）{
 $ isMulti = //执行某些命令或调用php函数（如果有的话）?; 
 echo $ isMulti; 
} 
  code>  pre  > 
  div>

答

You can use http://php.net/manual/en/class.imagick.php php class.

$files = scandir ('$tempSrc');
foreach ($files as $pdf) {
    $im = new Imagick();
    $im->pingImage($pdf);
    echo $isMulti = ($im->getNumberImages() > 1) ? true : false;
}
