PHP Search Engine Optimized URL
Why is this important to Google ?
Well, the same reason we find "http://webarto.com/13/php-search-engine-optimized-url" more self-explaining then "http://webarto.com/node.php?id=13".
The following code replaces all characters that are not alphanumeric, this way we clean URL of any unnecessary characters in link. Blank spaces are replaced by dash.
function google($string){
$string = strtolower($string);
$A = array('č','ć','ž','đ','š');
$B = array('c','c','z','dj','s');
$string = str_replace($A,$B,$string);
$string = preg_replace('/[^a-zA-Z0-9]/i','-',$string);
$string = preg_replace("/(-){2,}/",'$1',$string);
return $string;
}
