SMARTY : Remove whitespace at the beginning or end of my string in Smarty template?

Here's my string seperated by commas (,) $myStr = "One, Two,Three, Four , Five ,Six "

I am able successfully explode it {assign var="options" value=","|explode:$myStr}

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 SMARTY function equivalent to PHP's built-in trim($mystr) function. PHP trim will remove the start and end white-spaces if it present, otherwise return the actual string.

{section name=myname loop=$options}
   {$options[myname]}
{/section}

The code above would output:

One
Two
Three
[whitespace]Four[whitespace]
[whitespace]Five[whitespace]
Six[whitespace]

How can I trim whitespaces?

There is {strip}{/strip} in smarty. Whitespaces will be removed between theese tags.

{$var|substr:0:-1} would remove last character in your case the whitespace. {$var|substr:1} would remove the first character from string.

all php-functions can be used as modifiers implicitly (more below) and modifiers can be combined

from docs {$var|trim} in smarty is equal to trim($var) in php.

There is another way. Using {php}{/php} tags in in smarty to able to use php built-in trim() function, but that makes no sense to me. Why would you even want to put smarty variable back to php if it was included by php? Nonsense.

If the white space is just whitespace as in space characters, you can use the function trim() (Docs) to strip it. Replace $options[myname] with trim($options[myname]).

If it's the string "[whitespace]", you can use preg_replace() (Docs) like: preg_replace("/[whitespace]/","",$options[myname])
