-<p><strong>result()</strong></p>
-<p>This method returns the query result as an array of <strong>objects</strong>, or
-<strong>an empty array</strong> on failure. Typically you’ll use this in a foreach
-loop, like this:</p>

-<p><strong>result_array()</strong></p>

-<p><strong>row()</strong></p>
-<p>This method returns a single result row. If your query has more than
-one row, it returns only the first row. The result is returned as an
-<strong>object</strong>. Here’s a usage example:</p>
-<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$query</span> <span class="o">=</span> <span class="nv">$this</span><span class="o">-&gt;</span><span class="na">db</span><span class="o">-&gt;</span><span class="na">query</span><span class="p">(</span><span class="s2">&quot;YOUR QUERY&quot;</span><span class="p">);</span>

-<span class="p">}</span>
-</pre></div>
-</div>
-<p>If you want a specific row returned you can submit the row number as a
-digit in the first parameter:</p>
-<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$row</span> <span class="o">=</span> <span class="nv">$query</span><span class="o">-&gt;</span><span class="na">row</span><span class="p">(</span><span class="mi">5</span><span class="p">);</span>
-</pre></div>
-</div>
-<p>You can also add a second String parameter, which is the name of a class
-to instantiate the row with:</p>
-<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$query</span> <span class="o">=</span> <span class="nv">$this</span><span class="o">-&gt;</span><span class="na">db</span><span class="o">-&gt;</span><span class="na">query</span><span class="p">(</span><span class="s2">&quot;SELECT * FROM users LIMIT 1;&quot;</span><span class="p">);</span>

-</pre></div>
-</div>
-<p><strong>row_array()</strong></p>
-<p>Identical to the above <code class="docutils literal"><span class="pre">row()</span></code> method, except it returns an array.
-Example:</p>
-<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$query</span> <span class="o">=</span> <span class="nv">$this</span><span class="o">-&gt;</span><span class="na">db</span><span class="o">-&gt;</span><span class="na">query</span><span class="p">(</span><span class="s2">&quot;YOUR QUERY&quot;</span><span class="p">);</span>

-<span class="p">}</span>
-</pre></div>
-</div>
-<p>If you want a specific row returned you can submit the row number as a
-digit in the first parameter:</p>
-<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$row</span> <span class="o">=</span> <span class="nv">$query</span><span class="o">-&gt;</span><span class="na">row_array</span><span class="p">(</span><span class="mi">5</span><span class="p">);</span>
-</pre></div>
-</div>
-<p>In addition, you can walk forward/backwards/first/last through your
-results using these variations:</p>
-<blockquote>
-<div><div class="line-block">
-<div class="line"><strong>$row = $query-&gt;first_row()</strong></div>
-<div class="line"><strong>$row = $query-&gt;last_row()</strong></div>
-<div class="line"><strong>$row = $query-&gt;next_row()</strong></div>
-<div class="line"><strong>$row = $query-&gt;previous_row()</strong></div>
-</div>
-</div></blockquote>
-<p>By default they return an object unless you put the word “array” in the
-parameter:</p>
-<blockquote>
-<div><div class="line-block">
-<div class="line"><strong>$row = $query-&gt;first_row(‘array’)</strong></div>
-<div class="line"><strong>$row = $query-&gt;last_row(‘array’)</strong></div>
-<div class="line"><strong>$row = $query-&gt;next_row(‘array’)</strong></div>

-</div>
-<p><strong>unbuffered_row()</strong></p>
-<p>This method returns a single result row without prefetching the whole

-<p><strong>num_rows()</strong></p>
-<p>The number of rows returned by the query. Note: In this example, $query
-is the variable that the query result object is assigned to:</p>

-<p class="first admonition-title">Note</p>
-<p class="last">Not all database drivers have a native way of getting the total
-number of rows for a result set. When this is the case, all of

-<p><strong>num_fields()</strong></p>

-</pre></div>
-</div>
-<p><strong>free_result()</strong></p>
-<p>It frees the memory associated with the result and deletes the result
-resource ID. Normally PHP frees its memory automatically at the end of
-script execution. However, if you are running a lot of queries in a
-particular script you might want to free the result after each query
-result has been generated in order to cut down on memory consumption.</p>
