actually I want to conditionally of different file types so I want to check whether the extension is .ppt or .pptx or .pptm .ppm or any thing else.

You could do it this way.

$file = 'my-file.ppt';
$parts = pathinfo($file);
$extensions = array("ppt", "pptx", "pptm", "ppm");


if (in_array($parts['extension'], $extensions)) {
   echo "we have {$parts['extension']}";
}
else {
   echo "no matches";

}
