php - 如何拆分文本以匹配双引号加上尾随文本以点？

Question

如何获取双引号中有一个点必须分开的句子？

示例文档如下:

“Chess helps us overcome difficulties and sufferings,” said Unnikrishnan, taking my queen. “On a chess board you are fighting. as we are also fighting the hardships in our daily life.” he said.

我想得到这样的输出:

Array
(
    [0] =>"Chess helps us overcome difficulties and sufferings," said Unnikrishnan, taking my queen.
    [1] =>"On a chess board you are fighting. as we are also fighting the hardships in our daily life," he said.
 )

我的代码仍然由点爆炸。

function sample($string)
{
    $data=array();
    $break=explode(".", $string);
    array_push($data, $break);

    print_r($data);
}

我仍然对拆分关于双引号和点的两个定界符感到困惑。因为在双引号里面有一个包含点分隔符的句子。

Answer 1

(*SKIP)(*FAIL) 的完美示例:

“[^“”]+”(*SKIP)(*FAIL)|\.\s*
# looks for strings in double quotes
# throws them away
# matches a dot literally, followed by whitespaces eventually

---

在 PHP 中:

$regex = '~“[^“”]+”(*SKIP)(*FAIL)|\.\s*~';
$parts = preg_split($regex, $your_string_here);

这产生

Array
(
    [0] => “Chess helps us overcome difficulties and sufferings,” said Unnikrishnan, taking my queen
    [1] => “On a chess board you are fighting. as we are also fighting the hardships in our daily life.”
)
