在Laravel中使用SHA 1哈希

Question

I want to hash some strings of character using sha1 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

Please, i need assitance on this

Answer 1

All, i did was to ensure that the my varibales were fetched from the form and they were properly targeted. Hence, once this was done, i could concatenate and get the correct hash.

 $lice = $request->sname.$request->company.$request->effDate;
        //$lice = $serial->sname;
        $lice2= sha1($lice);
        $lice3 = chunk_split($lice2,5,'-');
        $lice4 =strtoupper($lice3);

       Serial::create([
        'sname' => $request->sname,
        'company' => $request->company,
        'effDate' => $request->effDate,
        'ltype' => $request->ltype
        ]);
