php - Laravel how to save data which in forloop -

i have data need save database. here's example controller:

public function saverequest(request $request){  $count = count($request->input('itemname')); $purchase = new prrequest;      ($i=0; $i<$count; $i++){             $data[] = array(             'pr_no' => $request->input('pr_no')[$i],                 'pr_date' => $request->input('pr_date')[$i],             'department' => $request->input('department')[$i],             'remarks' => $request->input('remarks')[$i],             'notes' => $request->input('notes')[$i],             'requested_by' => $request->input('requested_by')[$i],             'item_id' => $request->input('itemname')[$i],             'qty' => $request->input('qty')[$i],             'type' => $request->input('type')[$i],             'uom' => $request->input('uom'),             'pd_date' => $request->input('pd_date')[$i]             );         $purchase->fill($data[$i])->save();      }     return response::json($data, 200, array(), json_pretty_print); } 

i got error after clicking save button.

errorexception in helpers.php line 671: preg_replace(): parameter mismatch, pattern string while replacement array 

any solution? thank in advance.

you calling fill every iteration, s better build data batch insert

for ($i=0; $i<$count; $i++){         $data[] = array(         'pr_no' => $request->input('pr_no')[$i],             'pr_date' => $request->input('pr_date')[$i],         'department' => $request->input('department')[$i],         'remarks' => $request->input('remarks')[$i],         'notes' => $request->input('notes')[$i],         'requested_by' => $request->input('requested_by')[$i],         'item_id' => $request->input('itemname')[$i],         'qty' => $request->input('qty')[$i],         'type' => $request->input('type')[$i],         'uom' => $request->input('uom'),         'pd_date' => $request->input('pd_date')[$i]         );     $purchase->fill($data[$i])->save(); <-- remove }  db::table(table name) -> insert($data); <-- better, 1 query. 

hope helps.
