Use <?php where possible instead of <?. Search the group archives or
google why (searchterm: short_open_tags).

Should this not BE caught in the filter? One should use the PCRE (preg_*)
functions, and the match should not be greedy as in the patter above.

As indicated elsewhere, indentify the records in need of substitution in
your database using the answer givne in comp.databases.mysql

For those that do need substitution:

function _my_replace_function($match){
$return = substr($match[0],0,1); //first character stays the same
$return .= strtolower(substr($match[0],1)); //the rest should be lowercase
return $return;
}
$string =
preg_replace_callback('/\b\w*?[A-Z]{2,}\w*?\b/','_my_replace_function',$string);


Ideally, one should use a proper locale, substitute strtolower with
mb_strtolower and in UTF-8 mode use this pattern:
'/\b\w*?\p{Lu}{2,}\w*?\b/'

.... to be able to capture and change capitals like 'wÉÏrd' (which are not
in the normal [A-Z] range).
