Then reboot:

Use Imagick;

function Pdf2png ($pdf, $path, $page =-1)
{
if (!extension_loaded (' Imagick '))

return false;
}
if (!file_exists ($pdf))
{
echo dirname ($pdf);
echo "File not exit";
return false;
}

$im = new Imagick ();


$im->setresolution (120,120);
$im->setcompressionquality (100);
try {

}
}
return $Return;
}

function Cpdf2png ()
{
$path = "Public/files";//Make sure that the folder is in the current directory, because it is always used, so it is not detected

$scount =count ($s);
for ($i =0; $i < $scount; $i + +)
