Question

我想拆分包含大括号的字符串例如

string = "some-thing_text,text in rounded brackets(word first,word second),Text in curly brackets{some-text(some one,some two),some another},Text in square brackets[some text,some another{some like this(this1,this2)}]"

并输出：

Array
(
    [0] => some-thing_text
    [1] => text in rounded brackets(word first,word second)
    [2] => Text in curly brackets{some-text(some one,some two),some another}
    [3] => Text in square brackets[some text,some another{some like this(this1,this2)}]
)

Answer 1

,(?![^{]*})(?![^(]*\))(?![^\[]*\])

你可以使用它。参见演示。

Answer 2

你可以试试这个，

preg_split('~(?:\[.*?\]|\(.*?\)|\{.*?\})(*SKIP)(*F)|,~', $str);

(?:\[.*?\]|\(.*?\)|\{.*?\})匹配所有括号内的块。
(*SKIP)(*F)使上一场比赛失败。
,现在它与剩余字符串中的逗号匹配。
