Use imagick in PHP to convert PDF into images

In the PHP Manual, the description of imagick is really concise. For each member function, click to open and you will see the following text:

Warning
This function is currently not documented; only its argument list is available.

After just solving the PHP loading problem , it is very convenient to process images. I just found a paragraph on the Internet:

getImageWidth();
   $h = $imagick->getImageHeight();
   if ($w > $width || $h > $height)
   {
      if ($crop)
      {
         $imagick->cropThumbnailImage($width, $height);
      }
      else
      {
         $imagick->resizeImage($width, $height, Imagick::FILTER_LANCZOS, 1, true);
      }
   }
   $processed_image = $imagick->getImageBlob();
   return $processed_image;
}
$s=resize("123.jpg", 60, 40, 1);
echo $s;
?>

But what I want to use this extension to do is convert PDF to PNG. PDF!

setResolution(120,120);  
   $im->setCompressionQuality(100);
   if($page==-1)   
      $im->readImage($pdf);
   else
      $im->readImage($pdf."[".$page."]");
   foreach ($im as $Key => $Var)
   {  
       $Var->setImageFormat('png');  
       $filename = $path."/". md5($Key.time()).'.png';
       if($Var->writeImage($filename) == true)
       {  
           $Return[] = $filename;  
       }  
   }  
   return $Return;  
}  
$path="images";//请确保当前目录下有这个文件夹，由于一直要用，所以就不加检测了
$s=pdf2png("test.pdf",$path);
$scount=count($s);
for($i=0;$i<$scount;$i++)
{
   echo "Page ".($i+1)."
";
}
?>

Is it similar to the one above? But it always fails. There is an exception on the readImage side. Check the error output:

PHP Fatal error:  Uncaught exception 'ImagickException' with message 'PostscriptDelegateFailed `test.pdf': No such file or directory'

After searching on Baidu and Google for a long time, I finally had an idea. Didn't it say Postscript? I'm looking for it, I'm pretending.

This Postscript is actually GhostScript.

After installation, run, OK!
