Re: str_replace on words with an array

I never use this function, since I always use regular expressions, but according to the manual: If you don't need fancy replacing rules (like regular

         expressions), you should always use this function instead of
         ereg_replace() or preg_replace().

So, I assume your problem initially was that you were using regular expression syntax and this function doesn't accept regular expressions. Is your aim to get rid strings of all the items in the $noiseArray? Your $noiseArray includes the entire alpahabet, so it's no wonder that you end up with empty strings! Myron Dotan Cohen wrote:

Can you explain what you are trying to do with the ^ and $? What is a typical value of the original $searchQuery? Alan

The purpose of the ^ and the $ is to define the beginning and the end of a word: http://il2.php.net/regex I also tried str_replace( $noiseArray, " ", $searchQuery) but that was replacing the insides of words as well. And with the addition of the individual letters, that emptied the entire $searchQuery string! A typical value of $searchQuery could be "What is php?" or "What is open source".
