SMARTY : Remove whitespace at the beginning or end of my string in Smarty template?
<p>Here's my string seperated by commas (,)
<code>$myStr = "One, Two,Three, Four , Five ,Six "</code></p>

<p>I am able successfully explode it <code>{assign var="options" value=","|explode:$myStr}</code></p>

<p>But I also would like to remove whitespace at the beginning or end from each string when outputting it. In other words: I am looking for a <strong>SMARTY</strong> function equivalent to PHP's built-in <code>trim($mystr)</code> function. PHP trim will remove the start and end white-spaces if it present, otherwise return the actual string.</p>

<pre><code>{section name=myname loop=$options}
   {$options[myname]}
{/section}
</code></pre>

<p>The code above would output:</p>

<blockquote>
<pre><code>One
Two
Three
[whitespace]Four[whitespace]
[whitespace]Five[whitespace]
Six[whitespace]
</code></pre>
</blockquote>

<p>How can I trim whitespaces?</p>
