PHP form throws fatal error in version 8.01 when trying to use the count function for file upload. Data in not a countable function:

Fatal error: Uncaught TypeError: count(): Argument #1 ($value) must be of type Countable|array

Changing count to isset took care of the error but now the response email sent by the form is not encoded correctly. The and base64 encoding in the email appear in the email.

This was the code I had that worked before version 8.01:

if(count($files) > 0){
        for($i=0;$i<count($files);$i++){
            if(is_file($files[$i])){
                $message .= "--{$mime_boundary}n";
                $fp =    @fopen($files[$i],"rb");
                $data =  @fread($fp,filesize($files[$i]));
                @fclose($fp);
                $data = chunk_split(base64_encode($data));
                $message .= "Content-Type: application/octet stream;name="".basename($files[$i]).""n" . 
                "Content-Description: ".basename($files[$i])."n" .
                "Content-Disposition: attachment;n" . " filename="".basename($files[$i]).""; size=".filesize($files[$i]).";n" . 
                "Content-Transfer-Encoding: base64nn" . $data . "nn";
            }
        }
    }

So I tried casting the $files to an array:

$files = (array) $files;
    if(count($files) > 0){
        for($i=0;$i<count($files);$i++){
            if(is_file($files[$i])){
                $message .= "--{$mime_boundary}n";
                $fp =    @fopen($files[$i],"rb");
                $data =  @fread($fp,filesize($files[$i]));
                @fclose($fp);
                $data = chunk_split(base64_encode($data));
                $message .= "Content-Type: application/octet-stream; name="".basename($files[$i]).""n" . 
                "Content-Description: ".basename($files[$i])."n" .
                "Content-Disposition: attachment;n" . " filename="".basename($files[$i]).""; size=".filesize($files[$i]).";n" . 
                "Content-Transfer-Encoding: base64nn" . $data . "nn";
            }
        }
    }

This cleared the error too but produced emails with html code appearing in the email
So then I tried this:

    if(isset($files)){
        for($i=0;$i<count($files);$i++){
            if(is_file($files[$i])){
                $message .= "--{$mime_boundary}n";
                $fp =    @fopen($files[$i],"rb");
                $data =  @fread($fp,filesize($files[$i]));
                @fclose($fp);
                $data = chunk_split(base64_encode($data));
                $message .= "Content-Type: application/octet-stream; name="".basename($files[$i]).""n" . 
                "Content-Description: ".basename($files[$i])."n" .
                "Content-Disposition: attachment;n" . " filename="".basename($files[$i]).""; size=".filesize($files[$i]).";n" . 
                "Content-Transfer-Encoding: base64nn" . $data . "nn";
            }
        }
    }

It works as far as getting the uploaded file into the temp directory and moving it to the correct folder. It also doesn’t throw a fatal error, but the email response email looks like this:

Not sure why the change in count has affected the email body, but hoping someone here can lead me in the right direction. Thanks everyone for all the help.
