Php form validation minimum character need avoid white space?

Question

In our HR system i put a validation user have to put a note minimum 8 letters. but what if they don't put they can't punch in. but what they are doing is they are put 8 white space they can punch in :( so i want restrict them to put note avoid white space

if(empty($openPunch)){

            $currentTime = $req->time;
            if (strtotime($currentTime) >= strtotime('09:30')){
                if(strlen($req->note) < 8){
                $time = (strtotime($currentTime) - strtotime('09:30'));
                $minutes = floor($time / 60);
                $minute = $minutes%60;
                $hours = floor($time / 3600);
                return new IceResponse(IceResponse::ERROR,"Today you are late ".$hours.":".$minute." Hours    You Can't Punch in without Fill the Correct Reason");

    }
    }

    $openPunch = new Attendance();
}

This is like repairing a carburetor with a bandaid. Users will notice they can put 8 dots or anything else instead. — Julie Pelletier, Jul 22 '16 at 05:28
Why is it flagged as javascript? Do you want to perform a client-side check as well? — Arnauld, Jul 22 '16 at 05:34

and you would also provide validation to prevent special characters in order to make it more optimal. check this [link](http://stackoverflow.com/questions/16667329/special-character-validation) to know how to do it. – Prashanth Benny Jul 22 '16 at 05:42

Use trim() function

The trim() function removes whitespace and other predefined characters from both sides of a string.

      if(empty($openPunch)){

        $currentTime = $req->time;
        if (strtotime($currentTime) >= strtotime('09:30')){
            if(strlen(trim($req->note)) < 8){
            $time = (strtotime($currentTime) - strtotime('09:30'));
            $minutes = floor($time / 60);
            $minute = $minutes%60;
            $hours = floor($time / 3600);
            return new IceResponse(IceResponse::ERROR,"Today you are late ".$hours.":".$minute." Hours    You Can't Punch in without Fill the Correct Reason");

     }
    }

     $openPunch = new Attendance();
 }
