问题：

How would I go about splitting the word:我将如何拆分这个词：

oneTwoThreeFour

into an array so that I can get:放入一个数组中，以便我可以得到：

one Two Three Four

with preg_match ?与preg_match ？

I tired this but it just gives the whole word我累了，但它只是给出了整个词

$words = preg_match("/[a-zA-Z]*(?:[a-z][a-zA-Z]*[A-Z]|[A-Z][a-zA-Z]*[a-z])[a-zA-Z]*\b/", $string, $matches)`;
