To covert a string to SEO friendly, do this: 

<?php 
$realname = "This is the string to be made SEO friendly!" 

$seoname = preg_replace('/\%/',' percentage',$realname); 
$seoname = preg_replace('/\@/',' at ',$seoname); 
$seoname = preg_replace('/\&/',' and ',$seoname); 
$seoname = preg_replace('/\s[\s]+/','-',$seoname);    // Strip off multiple spaces 
$seoname = preg_replace('/[\s\W]+/','-',$seoname);    // Strip off spaces and non-alpha-numeric 
$seoname = preg_replace('/^[\-]+/','',$seoname); // Strip off the starting hyphens 
$seoname = preg_replace('/[\-]+$/','',$seoname); // // Strip off the ending hyphens 
$seoname = strtolower($seoname); 

echo $seoname; 
?> 

This will print: this-is-the-string-to-be-made-seo-friendly
