Question

I am getting strange behaviour from this function.

Input

    public function fetch_array($result_set) 
{
        $rows = array();
        while ($row = mysql_fetch_array($result_set)) 
        {
            $rows[] = $row;
            print_r($row);
            break;
        }
        return $rows;

}

I have made the function run once but it its duplicating a row from my MySQL query result.

Output

Array ( [0] => Sarah [first_name] => Sarah [1] => Palin [second_name] => Palin ) 

It should be

Correct Output

Array ( [first_name] => Sarah [second_name] => Palin ) 

I used this SO question example

Use mysql_fetch_array() with foreach() instead of while()

Not my query or Mysql result fault

What is going wrong here?

This is not an error, it’s the intended behavior of mysql_fetch_array() http://us.php.net/manual/en/function.mysql-fetch-array.php

You can either set the result_type flag, or you can just use mysql_fetch_assoc() instead. http://us.php.net/manual/en/function.mysql-fetch-assoc.php
