Here is my code... basically it finds any page-NUMBER- within a variable and then replaces it with a page url from an array

$content_text = preg_replace("/page-(\d+)-/sie", '$pageurl[$1]', $content_text);

It works a treat until the NUMBER it finds isn't in the array and it returns an error...

Is there another efficient way I could do this instead?

I liked my code above because it was simple but I may have to use more complex code...
