For user convenience, it might take an optional argument called <code>$name</code> that can be used to initialize one of the component parameters. For example, you can use the following constructor:</p>

<pre class="php"><span style="color: #000000; font-weight: bold;">class</span> myComponent implements Opt_Component_Interface
<span style="color: #009900;">&#123;</span>
    <span style="color: #000000; font-weight: bold;">private</span> <span style="color: #000088;">$_params</span> <span style="color: #339933;">=</span> <a href="http://www.php.net/array"><span style="color: #990000;">array</span></a><span style="color: #009900;">&#40;</span><span style="color: #009900;">&#41;</span><span style="color: #339933;">;</span>
&nbsp;
    <span style="color: #000000; font-weight: bold;">public</span> <span style="color: #000000; font-weight: bold;">function</span> __construct<span style="color: #009900;">&#40;</span><span style="color: #000088;">$name</span> <span style="color: #339933;">=</span> <span style="color: #0000ff;">''</span><span style="color: #009900;">&#41;</span>
    <span style="color: #009900;">&#123;</span>
        <span style="color: #b1b100;">if</span><span style="color: #009900;">&#40;</span><span style="color: #000088;">$name</span> <span style="color: #339933;">!=</span> <span style="color: #0000ff;">''</span><span style="color: #009900;">&#41;</span>
        <span style="color: #009900;">&#123;</span>
            <span style="color: #000088;">$this</span><span style="color: #339933;">-&gt;</span><span style="color: #004000;">set</span><span style="color: #009900;">&#40;</span><span style="color: #0000ff;">'name'</span><span style="color: #339933;">,</span> <span style="color: #000088;">$name</span><span style="color: #009900;">&#41;</span><span style="color: #339933;">;</span>
        <span style="color: #009900;">&#125;</span>
    <span style="color: #009900;">&#125;</span> <span style="color: #666666; font-style: italic;">// end __construct();</span>
&nbsp;
    <span style="color: #666666; font-style: italic;">// Other code...</span>
<span style="color: #009900;">&#125;</span> <span style="color: #666666; font-style: italic;">// end myComponent;</span></pre>

<p>Now, to specify the component name, we can pass it directly in the constructor:</p>

<pre class="php"><span style="color: #666666; font-style: italic;">// You can write</span>
<span style="color: #000088;">$component</span> <span style="color: #339933;">=</span> <span style="color: #000000; font-weight: bold;">new</span> myComponent<span style="color: #009900;">&#40;</span><span style="color: #0000ff;">'someName'</span><span style="color: #009900;">&#41;</span><span style="color: #339933;">;</span>
&nbsp;
<span style="color: #666666; font-style: italic;">// or</span>
<span style="color: #000088;">$component</span> <span style="color: #339933;">=</span> <span style="color: #000000; font-weight: bold;">new</span> myComponent<span style="color: #009900;">&#40;</span><span style="color: #009900;">&#41;</span><span style="color: #339933;">;</span>
<span style="color: #000088;">$component</span><span style="color: #339933;">-&gt;</span><span style="color: #004000;">set</span><span style="color: #009900;">&#40;</span><span style="color: #0000ff;">'name'</span><span style="color: #339933;">,</span> <span style="color: #0000ff;">'someName'</span><span style="color: #009900;">&#41;</span><span style="color: #339933;">;</span></pre>
