I want to replace 'and' with 'or' in a string but want it to only work on whole words. eg not 'sand'

I think that there's no word-boundaries support in ereg functions, so 
you have to use preg_replace.
<?php
echo preg_replace("/\\band\\b/", "or", "sand and and");
// prints: sand or or
?>
\b stands for word-boundary in PCRE (Perl compatible regexp) functions.
