    <p>I wrote this code :</p> <pre><code>$stmt = $link-&gt;prepare($statement_string); // [...] $result_m = $stmt-&gt;result_metadata(); if ($result_m) { $stmt-&gt;store_result(); // [...] $stmt-&gt;free_result(); $result_m-&gt;free(); } </code></pre> <p>Is that code right ? </p> <p>I read the doc <a href="http://www.php.net/manual/en/mysqli-stmt.result-metadata.php" rel="nofollow noreferrer">mysqli-stmt.result-metadata</a> and <a href="http://www.php.net/manual/en/mysqli-result.free.php" rel="nofollow noreferrer">mysqli-result.free doc</a>. I also read this post : <a href="https://stackoverflow.com/questions/3114972/do-ive-to-free-mysql-result-after-storing-it">...free-mysql-result-after-storing-it</a> but I didn't find my answer.</p> <p>EDIT :</p> <p>What I want to know is : will the <code>$stmt-&gt;free_result();</code> just liberate some memory allocation done by <code>$stmt-&gt;store_result();</code> or clearly free the memory of the <code>mysqli_result</code> object built by <code>$stmt-&gt;result_metadata();</code> ?</p>

    1. COI guess you should have read "[mysqli-stmt.free-result](http://www.php.net/manual/en/mysqli-stmt.free-result.php)" instead. +1 for reading the docs though.

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.
