In the above example, the template would contain two variables: {blog_title} and {blog_heading}</p> <p>There is no need to “echo” or do something with the data returned by $this->parser->parse(). It is automatically passed to the output class to be sent to the browser. However, if you do want the data returned instead of sent to the output class you can pass TRUE (boolean) as the third parameter:</p> <div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$string</span> <span class="o">=</span> <span class="nv">$this</span><span class="o">-></span><span class="na">parser</span><span class="o">-></span><span class="na">parse</span><span class="p">(</span><span class="s1">'blog_template'</span><span class="p">,</span> <span class="nv">$data</span><span class="p">,</span> <span class="k">TRUE</span><span class="p">);</span> </pre></div> </div> </div> <div class="section" id="variable-pairs"> <h3><a class="toc-backref" href="#id4">Variable Pairs</a><a class="headerlink" href="#variable-pairs" title="Permalink to this headline">¶</a></h3> <p>The above example code allows simple variables to be replaced. What if you would like an entire block of variables to be repeated, with each iteration containing new values? Consider the template example we showed at the top of the page:</p> <div class="highlight-ci"><div class="highlight"><pre><span></span><span class="o"><</span><span class="nx">html</span><span class="o">></span> <span class="o"><</span><span class="nx">head</span><span class="o">></span> <span class="o"><</span><span class="nx">title</span><span class="o">></span><span class="p">{</span><span class="nx">blog_title</span><span class="p">}</span><span class="o"></</span><span class="nx">title</span><span class="o">></span> <span class="o"></</span><span class="nx">head</span><span class="o">></span> <span class="o"><</span><span class="nx">body</span><span class="o">></span> <span class="o"><</span><span class="nx">h3</span><span class="o">></span><span class="p">{</span><span class="nx">blog_heading</span><span class="p">}</span><span class="o"></</span><span class="nx">h3</span><span class="o">></span> <span class="p">{</span><span class="nx">blog_entries</span><span class="p">}</span> <span class="o"><</span><span class="nx">h5</span><span class="o">></span><span class="p">{</span><span class="nx">title</span><span class="p">}</span><span class="o"></</span><span class="nx">h5</span><span class="o">></span> <span class="o"><</span><span class="nx">p</span><span class="o">></span><span class="p">{</span><span class="nx">body</span><span class="p">}</span><span class="o"></</span><span class="nx">p</span><span class="o">></span> <span class="p">{</span><span class="o">/</span><span class="nx">blog_entries</span><span class="p">}</span> <span class="o"></</span><span class="nx">body</span><span class="o">></span> <span class="o"></</span><span class="nx">html</span><span class="o">></span> </pre></div> </div> <p>In the above code you’ll notice a pair of variables: {blog_entries} data… {/blog_entries}. In a case like this, the entire chunk of data between these pairs would be repeated multiple times, corresponding to the number of rows in the “blog_entries” element of the parameters array.</p> <p>Parsing variable pairs is done using the identical code shown above to parse single variables, except, you will add a multi-dimensional array corresponding to your variable pair data. Consider this example:</p> <div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$this</span><span class="o">-></span><span class="na">load</span><span
