preg_split() 包含 '&' 的字符串问题

Question

我正在使用 preg_split() 从字符串中获取句子数组。

$sentences = preg_split("/([.?!\r\n]+)/", $text, 0, PREG_SPLIT_NO_EMPTY|PREG_SPLIT_DELIM_CAPTURE);

但是，例如，当 $text 包含“&”时：

$text = 'this is test. we are testing this & we are over.';

那么它会在“&”之后停止匹配。

Answer 1

您的 preg_split 正确处理带有＆符号的句子，例如：

$text = 'Sample sentence. Another sentence! Sentence with the special character & (ampersand). Last sentence.';
$sentences = preg_split("/([.?!\r\n]+)/", $text, 0, PREG_SPLIT_NO_EMPTY|PREG_SPLIT_DELIM_CAPTURE);
print_r($sentences);

输出：

Array
(
    [0] => Sample sentence
    [1] => .
    [2] =>  Another sentence
    [3] => !
    [4] =>  Sentence with the special character & (ampersand)
    [5] => .
    [6] =>  Last sentence
    [7] => .
)

Answer 2

你的脚本：

$text = 'this is test. we are testing this & we are over.';
$sentences = preg_split("/([.?!\r\n]+)/", $text, 0, PREG_SPLIT_NO_EMPTY|PREG_SPLIT_DELIM_CAPTURE);
echo '<pre>'.print_r($sentences, true).'</pre>';

我的输出：

Array
(
    [0] => this is test
    [1] => .
    [2] =>  we are testing this & we are over
    [3] => .
)

我不明白你的问题。
