427<p>The Template Parser Class can perform simple text substitution for
428pseudo-variables contained within your view files.
429It can parse simple variables or variable tag pairs.</p>
430<p>If you’ve never used a template engine,
431pseudo-variable names are enclosed in braces, like this:</p>

448<p>These variables are not actual PHP variables, but rather plain text

453<p class="last">CodeIgniter does <strong>not</strong> require you to use this class since
454using pure PHP in your view pages lets them run a little faster.
455However, some developers prefer to use a template engine if

481<h3><a class="toc-backref" href="#id2">Initializing the Class</a><a class="headerlink" href="#initializing-the-class" title="Permalink to this headline"></a></h3>
482<p>Like most other classes in CodeIgniter, the Parser class is initialized
483in your controller using the <code class="docutils literal"><span class="pre">$this-&gt;load-&gt;library()</span></code> method:</p>
484<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$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>
485</pre></div>
486</div>
487<p>Once loaded, the Parser library object will be available using:
488$this-&gt;parser</p>
489</div>
490<div class="section" id="parsing-templates">
491<h3><a class="toc-backref" href="#id3">Parsing templates</a><a class="headerlink" href="#parsing-templates" title="Permalink to this headline"></a></h3>
492<p>You can use the <code class="docutils literal"><span class="pre">parse()</span></code> method to parse (or render) simple templates,
493like this:</p>
494<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$data</span> <span class="o">=</span> <span class="k">array</span><span class="p">(</span>
495 <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>
496 <span class="s1">&#39;blog_heading&#39;</span> <span class="o">=&gt;</span> <span class="s1">&#39;My Blog Heading&#39;</span>
497<span class="p">);</span>
498
499<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>
500</pre></div>
501</div>
502<p>The first parameter contains the name of the <a class="reference internal" href="../general/views.html"><span class="doc">view
503file</span></a> (in this example the file would be called
504blog_template.php), and the second parameter contains an associative
505array of data to be replaced in the template. In the above example, the
506template would contain two variables: {blog_title} and {blog_heading}</p>
507<p>There is no need to “echo” or do something with the data returned by
508$this-&gt;parser-&gt;parse(). It is automatically passed to the output class
509to be sent to the browser. However, if you do want the data returned
510instead of sent to the output class you can pass TRUE (boolean) as the
511third parameter:</p>
512<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$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>
513</pre></div>

515</div>
516<div class="section" id="variable-pairs">
517<h3><a class="toc-backref" href="#id4">Variable Pairs</a><a class="headerlink" href="#variable-pairs" title="Permalink to this headline"></a></h3>
518<p>The above example code allows simple variables to be replaced. What if
519you would like an entire block of variables to be repeated, with each
520iteration containing new values? Consider the template example we showed
521at the top of the page:</p>
522<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>
523 <span class="o">&lt;</span><span class="nx">head</span><span class="o">&gt;</span>
524 <span class="o">&lt;</span><span class="nx">title</span><span class="o">&gt;</span><span class="p">{</span><span class="nx">blog_title</span><span class="p">}</span><span class="o">&lt;/</span><span class="nx">title</span><span class="o">&gt;</span>
525 <span class="o">&lt;/</span><span class="nx">head</span><span class="o">&gt;</span>
526 <span class="o">&lt;</span><span class="nx">body</span><span class="o">&gt;</span>

538<p>In the above code you’ll notice a pair of variables: {blog_entries}
539data… {/blog_entries}. In a case like this, the entire chunk of data
540between these pairs would be repeated multiple times, corresponding to
541the number of rows in the “blog_entries” element of the parameters array.</p>
542<p>Parsing variable pairs is done using the identical code shown above to
543parse single variables, except, you will add a multi-dimensional array
544corresponding to your variable pair data. Consider this example:</p>
