Hi,

I would like to share one of my code that is make clean SEO links

this function input text like post text etc and return clean seo links

function CleanSeoLink( $Raw ){
$Raw = trim($Raw);
$RemoveChars = array( "([\40])" , "([^a-zA-Z0-9-])", "(-{2,})" );
$ReplaceWith = array("-", "", "-");
return preg_replace($RemoveChars, $ReplaceWith, $Raw);
}
