Question

I have strings like:

$a = 'helloMister';
$b = 'doggyWaltz';
$c = 'bumWipe';
$d = 'pinkNips';

How can I explode at the capital letters? I have search on google for some time and came back with nothing!

If you want to split helloMister into hello and Mister you can use preg_split to split the string at a point just before the uppercase letter by using positive lookahead assertion:

$pieces = preg_split('/(?=[A-Z])/',$str);

and if you want to split it as hello and ister you can do:

$pieces = preg_split('/[A-Z]/',$str);
