Question

鉴于此字符串：

$somethingawesome = '<[return date("Y-m-d", strtotime("yesterday"));]>,<[return "cool!";]>,TRUE,foo';

如何获得这样的数组：

Array
(
[0] => <[return date("Y-m-d", strtotime("yesterday"));]>

[1] => <[return "cool!";]>

[2] => TRUE

[3] => foo
)

Answer 1

根据您给定的字符串，您可以使用以下内容...

$results = preg_split('/(?:<[^>]*>)?\K,/', $str);
print_r($results);

输出

Array
(
    [0] => <[return date("Y-m-d", strtotime("yesterday"));]>
    [1] => <[return "cool!";]>
    [2] => TRUE
    [3] => foo
)

当然，你可以匹配所有而不是使用拆分..

preg_match_all('/<[^>]+>|[^><,]+/', $str, $matches);

Answer 2

 ,(?=(?:[^\]\[]*\[[^\]]*\])*[^\]\[]*$)

试试这个。参见demo.Replace by \n。
