Split word by capital letter

Question

I want to split a word by capital letter in PHP

For example:

$string = \"facebookPageUrl\";

I want it like this:

$a         


        

Answer 1

You can use preg_split with the a look-ahead assertion:

preg_split('/(?=\p{Lu})/u', $str)

Here \p{Lu} is a character class of all Unicode uppercase letters. If you just work with US-ASCII characters, you could also use [A-Z] instead.

Answer 2

$string = "facebookPageUrl";

preg_match_all('((?:^|[A-Z])[^A-Z]*)', $string, $matches);
var_dump($matches);
