PHP checks the audio and video file formats and verifies whether the audio and video are forged

The method of processing images learned from the Internet, detecting forged images with modified suffix names:

<code>//检测伪造
    public function checkFlag() {
        
        $this->flag=@getimagesize($this->fileInfo['tmp_name']);
        if ($this->flag) {
            return true;
        }else {
            $this->error="请上传合法文件";
            return false;
        }
    }</code>

I would like to ask if there is a method similar to getimagesize to detect audio and video, MP3, MP4.

<code>$finfo = finfo_open(FILEINFO_MIME);
$mimetype = finfo_file($finfo, $inputFileName);</code>

You can judge by reading the first 8 bytes.
