Using SHA 1 Encryption in Laravel : I want to encrypt some strings of character using sha1 hash in laravel. but no matter what the strings are, they are all returning the same hash. Please, i need to know why it is so, or what am i doing wrong . See below my code:

    $lice = $serial->sname.$serial->company.$serial->effDate.$serial->ltype;
            //$serial->sname is MTS;
            //$serial->company is Godowns Technology;
            //$serial->effDate is 2017-01-24;
            //$serial->ltype is Trial
    
            $lice2= sha1($lice);
            $lice3 = chunk_split($lice2,5,'-');
            $lice4 =strtoupper($lice3);
      based on the information above, the $lice4 is always return: 
    DA39A-3EE5E-6B4B0-D3255-BFEF9-56018-90AFD-80709
