使用php preg_match（正则表达式）将camelCase单词拆分为单词

Question

我将如何拆分单词：

oneTwoThreeFour

放入数组，这样我就可以得到：

one Two Three Four

与preg_match？

我很累，但这只是整个词

$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)`;

Answer 1

您还可以preg_match_all用作：

preg_match_all('/((?:^|[A-Z])[a-z]+)/',$str,$matches);

说明：

(        - Start of capturing parenthesis.
 (?:     - Start of non-capturing parenthesis.
  ^      - Start anchor.
  |      - Alternation.
  [A-Z]  - Any one capital letter.
 )       - End of non-capturing parenthesis.
 [a-z]+  - one ore more lowercase letter.
)        - End of capturing parenthesis.
