You can make SEO Friendly url easily in php.

function friendlyURL($string){
	$string = preg_replace("`\[.*\]`U","",$string);
	$string = preg_replace('`&(amp;)?#?[a-z0-9]+;`i','-',$string);
	$string = htmlentities($string, ENT_COMPAT, 'utf-8');
	$string = preg_replace( "`&([a-z])(acute|uml|circ|grave|ring|cedil|slash|tilde|caron|lig|quot|rsquo);`i","\\1", $string );
	$string = preg_replace( array("`[^a-z0-9]`i","`[-]+`") , "-", $string);
	return strtolower(trim($string, '-'));
}

usage:

$myFriendlyURL = friendlyURL("Barca rejects FIFA statement on Olympics row");
echo $myFriendlyURL; // will echo barca-rejects-fifa-statement-on-olympics-row

Jquery is the another lightweight JavaScript Library for rapid web development.

Anyway, do you see the problem that might arise when you try to embed your jQuery code or any other javascript library (like Prototype, MooTools, Extjs, etc.) that uses $ as a function name in the ?

The solution:
Use Smarty’s {literal}…{/literal} directives to tell Smarty parsing engine that it should not interpret the code within the block. Smarty will not parse the code which is inside of literal block.

Example:

User
<script type=”text/javascript”>// <![CDATA[
{literal}
$(document).ready(function(){
$(".clazz").css("color", "red");
});
{/literal}
// ]]></script>

User Information:

Name: {$name}
