Answer 1

You can write this query in laravel like below.
$query = DB::table($table);
if(is_array($condition)) {
foreach ($condition as $key => $value) {
$query->where($key, "'" . $value . "'");
}
}
$result = $query->get();
if (count($result) > 0) {
return $result;
} else {
return false;
}

Let me assume that your eloquent model class is SomeModel. Then You could try like the following for first query/method-
$query = new SomeModel();
if(is_array($condition))
{
foreach ($condition as $key => $value)
$query = $query->where($key, $value);
}
$result = $query->get();
And for the second-
if(is_array($data)){
$query = new SomeModel();
foreach ($data as $key => $value)
$query->$key = $value;
$query->save();
}
Hope it solves your problem :)
