My correct SQL query (tested on phpmyadmin) is returning wrong result in PHP

Let me explain. I have a simple query which works when I tested it on phpmyadmin but it does not return the right answer in my web application.

This is the function that runs the query:

function GetProductsFromCategoryId($categoryId)
{
    global $db;
    $query = '
        SELECT *
        FROM `products`
        WHERE categoryID = 3';
    try {
        $statement = $db->prepare($query);
        //$statement->bindValue(':categoryId', $categoryId);
        $statement->execute();
        $result = $statement->fetch();
        $statement->closeCursor();
        return $result;
    } catch (PDOException $e) {
        $error_message = $e->getMessage();
        display_db_error($error_message);
    }
}

usually categoryID = $categoryID but I hard coded it with "3" because I wanted to see the results. There is whole other database file which handles the connection and I can post them if you want but the other functions work fine. This is a template that I use from Murach's php book ch 24. This function is my own, slightly modified.

With SELECT *, the function should return 2 arrays for for each product as you will see later when I post my result from phpmyadmin. Instead, it only return 1 array for one product.

This is the query I ran in phpmyadmin:

SELECT * FROM `products` WHERE categoryID=3;

and the result is:

        9   3   ludwig  Ludwig 5-piece Drum Set with Cymbals    This product includes a Ludwig 5-piece drum set an...   699.99  30.00   2010-07-30 12:46:40

So, as you can see, it should return 2 array as that is what the fetch() function should do but it only returns one array. I have xdebug set up with netbeans and looking at the variable $result, it has 1 array with productName "Ludwig 5-piece..."

I have been stuck on this for a 3 days and I have zero idea why it does not work. Please please help!

Thanks!!!

The first column is the productID and the second column is the categoryID.


Your $statement->fetch() only returns a single row from the database. See PDOStatement::fetch(). I think you want PDOStatement::fetchAll() instead to return all rows from your query.


PDOStatement::fetch() only returns one row at a time. You must call it iteratively to get the remaining rows.
