我正在尝试使用 preg_split 拆分字符串,但我想包含分隔符,并且我不想捕获空字符串。我该怎么做?
$inputX = "hello1.hello2.";
$tempInput = preg_split( "~(\?|\.|!|\,)~", $inputX); //split the input at .!?,
print_r($tempInput)
结果:
Array ( [0] => hello1 [1] => hello2 [2] => )
需要结果:
Array ( [0] => hello1. [1] => hello2.
使用这个正则表达式:
(?<=[.!?])(?!$|[.!?])
解释:
(?<= # looks for positions after
[.!?] # one of these three characters
) #
(?! # but not
$ # at the end
| # OR
[.!?] # before one of these three characters
) #
希望有帮助。
