Regex To Break Up camelCase String PHP

Let say I have the following string:

getPasswordLastChangedDatetime

How would I be able to split that up by capital letters so that I would be able to get:

get
Password
Last
Changed
Datetime

If you only care about ASCII characters:

$parts = preg_split("/(?=[A-Z])/", $str);

DEMO

The (?= ..) construct is called lookahead [docs].

This works if the parts only contain a capital character at the beginning. It gets more complicated if you have things like getHTMLString. This could be matched by:

$parts = preg_split("/((?<=[a-z])(?=[A-Z])|(?=[A-Z][a-z]))/", $str);

Use this: [a-z]+|[A-Z][a-z]* or \p{Ll}+|\p{Lu}\p{Ll}*

No need to over complicated solution. This does it

preg_replace('/([A-Z])/',"\n".'$1',$string);

This doens't take care of acronyms of course
