I am trying to nail down a bit of code for changing processor names depending
on matches.
Problem i am having is the replacement takes place then it seems to do it
again replacing the text just replaced as there are similar matches
afterwards. example (easier)

$string = "The new Intel Core 2 Duo T8300";

$patterns = array("/Intel Core 2 Duo/","/Intel Core 2/");

$replacements = array("/Intel Core 2 Duo Processor Technology/","/Intel Core
2 Processor Technology/");

I would expect to get the following:

The new Intel Core 2 Duo Processor Technology T8300

but i get

The new Intel Core 2 Processor Technology Duo Processor Technology T8300

I can see why its doing it, reading the string in and making the replacement
but then reading the string in for the next pattern, but i don't want it to
do this. How do i stop preg_replace from reading in the same part of the
string that has been replaced already?

(it's a bad day! :( )
