 as a string rather than sending it
to your browser. This can be useful if you want to process the data in
some way. If you set the parameter to TRUE (boolean) it will return
data. The default behavior is false, which sends it to your browser.
Remember to assign it to a variable if you want the data returned:</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"
