获取大括号之间的数据

Question

$string = "[john] sometext [rohn] sometext [mohan]";

如何获取不同数组中的方括号之间的数据。

我有以下代码

preg_match_all("/\((?:[^()]|(?R))+\)/",  $string , $matches);

上面的代码按照我需要的方式非常适合大括号，但是如何使它适合方括号？

Answer 1

$string = "[john] sometext [rohn] sometext [mohan]";
preg_match_all("/\[([^]]+)\]/",  $string , $matches);
print_r($matches);

输出：

Array
(
    [0] => Array
        (
            [0] => [john]
            [1] => [rohn]
            [2] => [mohan]
        )

    [1] => Array
        (
            [0] => john
            [1] => rohn
            [2] => mohan
        )

)

说明：

\[          : opening square bracket
(           : start group 1
    [^]]+   : 1 or more any character that is not closing square bracket
)           : end group 1
\]          : closing square racket
