-<p>The Template Parser Class can perform simple text substitution for

-It can parse simple variables or variable tag pairs.</p>
-<p>If you’ve never used a template engine,
-pseudo-variable names are enclosed in braces, like this:</p>

-<p>Like most other classes in CodeIgniter, the Parser class is initialized
-in your controller using the <code class="docutils literal"><span class="pre">$this-&gt;load-&gt;library()</span></code> method:</p>
-<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$this</span><span class="o">-&gt;</span><span class="na">load</span><span class="o">-&gt;</span><span class="na">library</span><span class="p">(</span><span class="s1">&#39;parser&#39;</span><span class="p">);</span>
-</pre></div>
-</div>
-<p>Once loaded, the Parser library object will be available using:
-$this-&gt;parser</p>
-</div>
-<div class="section" id="parsing-templates">
-<h3><a class="toc-backref" href="#id3">Parsing templates</a><a class="headerlink" href="#parsing-templates" title="Permalink to this headline">¶</a></h3>
-<p>You can use the <code class="docutils literal"><span class="pre">parse()</span></code> method to parse (or render) simple templates,
-like this:</p>
-<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$data</span> <span class="o">=</span> <span class="k">array</span><span class="p">(</span>
- <span class="s1">&#39;blog_title&#39;</span> <span class="o">=&gt;</span> <span class="s1">&#39;My Blog Title&#39;</span><span class="p">,</span>
- <span class="s1">&#39;blog_heading&#39;</span> <span class="o">=&gt;</span> <span class="s1">&#39;My Blog Heading&#39;</span>
-<span class="p">);</span>
-
-<span class="nv">$this</span><span class="o">-&gt;</span><span class="na">parser</span><span class="o">-&gt;</span><span class="na">parse</span><span class="p">(</span><span class="s1">&#39;blog_template&#39;</span><span class="p">,</span> <span class="nv">$data</span><span class="p">);</span>
-</pre></div>
-</div>
-<p>The first parameter contains the name of the <a class="reference internal" href="../general/views.html"><span class="doc">view
-file</span></a> (in this example the file would be called
-blog_template.php), and the second parameter contains an associative
-array of data to be replaced in the template. 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
-$this-&gt;parser-&gt;parse(). It is automatically passed to the output class
-to be sent to the browser. However, if you do want the data returned
-instead of sent to the output class you can pass TRUE (boolean) as the
-third parameter:</p>
-<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$string</span> <span class="o">=</span> <span class="nv">$this</span><span class="o">-&gt;</span><span class="na">parser</span><span class="o">-&gt;</span><span class="na">parse</span><span class="p">(</span><span class="s1">&#39;blog_template&#39;</span><span class="p">,</span> <span class="nv">$data</span><span class="p">,</span> <span class="k">TRUE</span><span class="p">);</span>
-</pre></div>
-</div>

-<div 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">&lt;</span><span class="nx">html</span><span class="o">&gt;</span>
- <span class="o">&lt;</span><span class="nx">head</span><span class="o">&gt;</span>

- <span class="o">&lt;/</span><span class="nx">head</span><span class="o">&gt;</span>
- <span class="o">&lt;</span><span class="nx">body</span><span class="o">&gt;</span>
- <span class="o">&lt;</span><span class="nx">h3</span><span class="o">&gt;</span><span class="p">{</span><span class="nx">blog_heading</span><span class="p">}</span><span class="o">&lt;/</span><span class="nx">h3</span><span class="o">&gt;</span>
-
- <span class="p">{</span><span class="nx">blog_entries</span><span class="p">}</span>
- <span class="o">&lt;</span><span class="nx">h5</span><span class="o">&gt;</span><span class="p">{</span><span class="nx">title</span><span class="p">}</span><span class="o">&lt;/</span><span class="nx">h5</span><span class="o">&gt;</span>
- <span class="o">&lt;</span><span class="nx">p</span><span class="o">&gt;</span><span class="p">{</span><span class="nx">body</span><span class="p">}</span><span class="o">&lt;/</span><span class="nx">p</span><span class="o">&gt;</span>
- <span class="p">{</span><span class="o">/</span><span class="nx">blog_entries</span><span class="p">}</span>
-
- <span class="o">&lt;/</span><span class="nx">body</span><span class="o">&gt;</span>
-<span class="o">&lt;/</span><span class="nx">html</span><span class="o">&gt;</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">$this</span><span class="o">-&gt;</span><span class="na">load</span><span class="o">-&gt;</span><span class="na">library</span><span class="p">(</span><span class="s1">&#39;parser&#39;</span><span class="p">);</span>
-
-<span class="nv">$data</span> <span class="o">=</span> <span class="k">array</span><span class="p">(</span>
