splitting a string

[mrithula]

The sample string is KmSO4

 

Every upper case alphabet should be identified and splitted until another upper case alphabet comes.

 

the string should be splitted so that output array looks like this

Array ( [0] => Km [1] => S [2]=>O4 )

 

can any one help regarding this issue?

You could use a regular expression to look for points in the string which have a capital letter immediately following it. How familiar are you with regular expressions? (It's OK to say not at all!)

 

$array = preg_split('/(?!^)(?=[A-Z])/', 'KmSO4');

 

If that just looks like an indecipherable mess, let us know. The job can likely also be done with functions that you are more familiar with (do let us know!).
