note 43174 added to function.str-ireplace

Here's a script that replaces certain words in a posted comment into advertisments. Example, comment sent by HTML form... "...so I'm buying a new car at the weekend. It's been a great day today though..." ...comment edited by PHP... "<a href='/keyword/search/car' alt='Look on the internet for a new car!'>car</a>" "...so I'm buying a new <a href='/keyword/search/car' alt='Look on the internet for a new car!'>car</a> at the weekend. It's been a great day today though..." THIS REQUIRES PHP 5 FOR THIS TO WORK.
