    <p>I'm not sure if this appropriate on here since it is more of a understanding issue on my part but I''m curious to know why I receive this output:</p> <pre><code>Response id: 3 Question id: 1 Question: What is my middle name? Title: How Well Do You Know Michael Array ( [0] =&gt; Array ( [0] =&gt; 3 [r_id] =&gt; 3 [1] =&gt; 1 [question_id] =&gt; 1 [2] =&gt; What is my middle name? [question] =&gt; What is my middle name? [3] =&gt; How Well Do You Know Michael [title] =&gt; How Well Do You Know Michael ) ) </code></pre> <p>when I run this PHP script:</p> <pre><code>// Grab the response data from the database to generate the form $query = "SELECT qr.response_id AS r_id, qr.question_id, q.question, quiz.title " . "FROM quiz_response AS qr " . "INNER JOIN question AS q USING (question_id) " . "INNER JOIN quiz USING (quiz_id) " . "WHERE qr.user_id = '" . $_SESSION['user_id'] . "'"; $data = mysqli_query($dbc, $query) or die("MySQL error: " . mysqli_error($dbc) . "&lt;hr&gt;\nQuery: $query"); $questions = array(); while ($row = mysqli_fetch_array($data)) { echo 'Response id: ' . $row['r_id'] . 'Question id: ' . $row['question_id'] . ' Question: ' . $row['question'] . ' Title: ' . $row['title'] . '&lt;br /&gt;'; array_push($questions, $row); } print_r($questions); </code></pre> <p>It seems as though there are two entries for each piece of data. For example, there are two entries of the 'Response id' under index [0] and [r_id]. Both equal 3. <strong>Is it a delirious fear of mine worrying about duplicated data in my array?</strong> I'm thinking of the future when I'm doing 10's of queries at a time and whether this will affect speed or accuracy. Any input is greatly appreciated!</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
