PHP - 捕获正则表达式匹配以及不匹配的余数

Question

For a string like asdftheremainderhere, what is a simple way to split the string to asdf and theremainderhere using a regex to match asdf?

I tried using:

preg_match('/asdf|ghik/', 'asdftheremainderhere', $matches);`

But only asdf is the only element of $matches.

Answer 1

You can use preg_split with \K which save delimiter

print_r(preg_split('/(asdf|ghik)\K/', 'asdftheremainderhere'));

result

Array
(
    [0] => asdf
    [1] => theremainderhere
)
