Question

Here is my code to retrive value from database

    $query = "SELECT * FROM t_contact
                      WHERE id = {$project_details_id} LIMIT 1";
     $all_post_info1 = mysql_query($query, $connection);
     confirm_query($all_post_info1);
     $project_details = mysql_fetch_array(show_project_details($project_details_id));

     foreach ($project_details as $fieldname) {
        echo $fieldname . "</br>";
     }

And

function confirm_query($confirm_result) {

    if (!$confirm_result) {
        die("Database query failed1: " . mysql_error());
    }
}

And i get output twice for each field. There are 27 column in my database and i get 54 output.
For example, there are name, email column in database and my output shows like

name
name
email
email 

Some please tell me what is wrong with this code.

By using MYSQL_BOTH (default), you’ll get an array with both associative and number indices.

That’s because your $project_details actually looks [something] like this:

$project_details = array(
  [0] => 'name',
  [name] => 'name',
  [1] => 'email',
  [email] => 'email'
);

Try specifying MYSQL_ASSOC in your mysql_fetch_array call.
