How to update a current row on Parse.com using php

Question

I want to update single row base on id, i have questions table and there is column question_id, which has unique date for each row. Now i want to update that row column based on that question_id. I have code written below, but not getting success. It created New Record not update old record. I want to update old record. I have tried both ParseObject and ParseQuery but not getting success.

      $query = new ParseObject("question");
      $query->equalTo("question_id", "2");
      $query->set("correct_percentage", "55.5");
      $query->save();

You should load the object in question first, manipulate the data and then save it. Your current code, as you already noticed, simply creates new objects each time it is run.

// Fetch the question object where question_id == 2
$query = new ParseQuery("question");
$query->equalTo("question_id", "2");
$question = $query->first();

// .. optionally verify that $question has a value ...

// Manipulate the object and save it
$question->set("correct_percentage", "55.5");
$question->save();

Does the question you are querying actually exist in your database?
