How does one break a string down by capital letters with PHP?

Question

I have a string: CamelCaseString

I want to explode(), split(), or some better method on capital letters to break this string down into the individual words.

What's the simplest way to do this?

This link is to a slightly different question, but I think the answer will generally be more useful than the answers to the current question on this page: How can I add a space in string at capital letters, but keep continuous capitals together using PHP and a Regex?

Answer 1

You should use regular expressions. Try this: preg_match_all('/[A-Z][^A-Z]*/', "CamelCaseString", $results);

The array containing all the words will be saved in $results[0].
