使用php preg_match(正则表达式)将camelCase单词拆分为单词 [英] Split camelCase word into words with php preg_match (Regular Expression)

问题描述

我将如何拆分单词:

oneTwoThreeFour

放入一个数组，这样我就可以得到:

into an array so that I can get:

one Two Three Four

带有preg_match吗?

我很累，但这只是整个单词

I tired this but it just gives the whole word

$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)`;

推荐答案

您也可以将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.
