I have the following code at the moment:

php Code:

$szChem = 'H2OCe';
$aMatches = preg_split('~([^\P{Lu}]+)~', $szChem, null, PREG_SPLIT_DELIM_CAPTURE);

print_r($aMatches);

Which outputs:

Code:

Array
(
    [0] => 
    [1] => H
    [2] => 2
    [3] => O
    [4] => 
    [5] => C
    [6] => e
)

I could remove the flag PREG_SPLIT_DELIM_CAPTURE but I want the uppercase character I'm splitting it on. So if things were going right for me the array would look like so:

Code:

Array
(
    [0] => H2
    [1] => O
    [2] => Ce
)

But I just can't seem to get it. Any ideas?
