Hi there,
I want to create a function which will replace certain words out of a
text with internal links. That works so far, but if I have two matches,
I end up with invalid html code.
Example:
Welpen /hunde
Chihuahua Welpen /hunde,chihuahua
function seo_internal_links($str, $links, $limit) {
foreach($links AS $link){
$pattern[$k] = "~\b($link[phrase])\b~i";
$replace[$k] = '<a href="'.$link[link].'">\\1</a>';
$k++;
}
return preg_replace($pattern,$replace,$str, $limit);
}
seo_internal_links($ad[text], $seo_internal_links, $limit = 1);
This will result in:
<a href="//hunde,chihuahua">Chihuahua <a href="/hunde">Welpen</a></a>
Has somebody an idea on how to avoid this? I would also like to limit
the amount of hits, but the limit in preg_replace accounts only for
unique words, not the whole array.
Thank you for any hint,
Merlin
