please try this:-

public function bbcreate(Request $request){

    $biniyojan_details = new BiniyojanDetails();
    $biniyojan_details->school = $request->school;
    $biniyojan_details->source = $request->source;
    $biniyojan_details->kriyakalap = $request->kriyakalap;
    $biniyojan_details->debit_credit = $request->debit_credit;
    $biniyojan_details->debit_credit_type = $request->debit_credit_type;
    $biniyojan_details->cash = $request->cash;

    $biniyojan_details->save();

    if(!empty($request->school)){
        for($i=0; $i< count($request->school); $i  ){
            $biniyojan              = new Biniyojan();
            $biniyojan->details_id  = $biniyojan_details->id;
            $biniyojan->date        = $request->date[$i];
            $biniyojan->ab          = $request->ab[$i];
            $biniyojan->school      = $request->school[$i];
            $biniyojan->behora      = $request->behora[$i];
            $biniyojan->save();

        }

    }
    return redirect()->back()->with('status', 'Inserted');
}

As you said you are trying to insert multiple row data.

Then You must convert array into json to store it into database.

Do like this - json_encode($request->school,true);
