php - 用方括号分割字符串

Question

我正在尝试使用 preg_split 拆分此文本

Yes, it was great. [I have no ideas how great it was.]

进入这个数组：

['Yes', 'it', 'was', great', '[I have no ideas how great it was.]'

但是我不知道怎么...

Answer 1

$keywords = preg_split("/[\s,.]+(?![^[]*])/", "Yes, it was great. [I have no ideas how great it was.]");
print_r($keywords);
