在 PHP 中将段落分解为句子

我一直在使用

explode(".",$mystring)

将段落拆分成句子。然而，这不包括用不同标点符号结束的句子，例如！ ？ : ;

有没有办法使用数组而不是单个字符作为分隔符？或者还有另一种使用各种标点符号进行拆分的巧妙方法吗？

I tried

explode(("." || "?" || "!"),$mystring)

希望如此，但没有成功...

您可以使用preg_split() http://php.net/preg_split结合一个PCRE 前瞻条件 http://www.regular-expressions.info/lookaround.html每次出现后分割字符串., ;, :, ?, !, .. 同时保持实际标点符号完整：

Code:

$subject = 'abc sdfs.    def ghi; this is [email protected] /cdn-cgi/l/email-protection! asdasdasd? abc xyz';
// split on whitespace between sentences preceded by a punctuation mark
$result = preg_split('/(?<=[.?!;:])\s+/', $subject, -1, PREG_SPLIT_NO_EMPTY);
print_r($result);

Result:

Array
(
    [0] => abc sdfs.
    [1] => def ghi;
    [2] => this is an.e[email protected] /cdn-cgi/l/email-protection!
    [3] => asdasdasd?
    [4] => abc xyz
)

您还可以添加缩写黑名单（Mr.、Mrs.、Dr.、..）not通过插入否定的lookbehind断言将其分成自己的句子：

$subject = 'abc sdfs.   Dr. Foo said he is not a sentence; asdasdasd? abc xyz';
// split on whitespace between sentences preceded by a punctuation mark
$result = preg_split('/(?<!Mr.|Mrs.|Dr.)(?<=[.?!;:])\s+/', $subject, -1, PREG_SPLIT_NO_EMPTY);
print_r($result);

Result:

Array
(
    [0] => abc sdfs.
    [1] => Dr. Foo said he is not a sentence;
    [2] => asdasdasd?
    [3] => abc xyz
)
