str_replace ignore case?

[kark_1999]

I want to highlight all the search terms in my results. It currently works, but only if the case matches. Does anyone know a way that I can ignore case?

I'm currently using....

$detailtext= str_replace($sKeywords, $highlighted_words, $detailtext);

Any suggestions?

Thanks.

If you're using php5, use str_ireplace. Otherwise, look at this thread
