Question

我想从文本中得到一些句子。

下面是示例文本，

狮ry低声打断。渡渡鸟说，“一点也不。”指着木头混乱的喧闹声-（尽管她对他很想。格里芬低声打断了。“一点也不，”渡渡鸟指着那混乱的东西说。树林的喧闹声-（尽管她向你考虑了他。狮phon低声打断了。“一点也不，”渡渡鸟指着木头的混乱叫声说-（尽管

到目前为止，我已经能够从一个较大的文本中获得30个单词，但是最后，我的句子不完整，我想删除这样的句子。

这里是获取30个单词的功能，

/**
 * @param $sentence
 * @param int $count
 * @return mixed
 */
function get_words($sentence, $count = 30) {
    preg_match("/(?:\w+(?:\W+|$)){0,$count}/", $sentence, $matches);
    return $matches[0];
}

我从下面的问题中使用了上面的功能

当我在文本上方传递给函数时，我得到了这样的输出，

狮ry低声打断。 “一点也不，”渡渡鸟说，指着木头的混乱叫声-（尽管她对你算是他了。狮phon打断了

这里的最后一句话是不完整的，我不希望在输出中这样。

有什么办法可以做到这一点？

我正在使用PHP和Laravel，任何帮助和建议都将受到赞赏。

下面的代码可能会对您有所帮助。

<?php
$sen="Gryphon interrupted in a low voice. 'Not at all,' said the Dodo, pointing to the confused clamour of the wood--(she considered him to you, Though.Gryphon interrupted in a low voice. 'Not at all,' said the Dodo, pointing to the confused clamour of the wood--(she considered him to you, Though.Gryphon interrupted in a low voice. 'Not at all,' said the Dodo, pointing to the confused clamour of the wood--(she considered him to you, Though.";
$cropped_data =  get_words($sen);
$strlength = strlen ( $cropped_data );
$remains=  complete_sentence(substr($sen,$strlength));

function complete_sentence($content) {
    $pos = strpos($content, '.');
    return substr($content, 0, $pos+1);
}

function get_words($sentence, $count = 30) {
    preg_match("/(?:\w+(?:\W+|$)){0,$count}/", $sentence, $matches);
    return $matches[0];
}

echo "complete sentence<br/>".$cropped_data.$remains;
?>

谢谢。

function get_words($sentence, $count = 30) {

  preg_match("/(?:w+(?:W+|$)){0,$count}/", $sentence, $matches);

  return $matches[0];
};

$sentence = "Gryphon interrupted in a low voice. 'Not at all,' said the Dodo, pointing to the confused clamour of the wood--(she considered him to you, Though.Gryphon interrupted in a low voice. 'Not at all,' said the Dodo, pointing to the confused clamour of the wood--(she considered him to you, Though.Gryphon interrupted in a low voice. 'Not at all,' said the Dodo, pointing to the confused clamour of the wood--(she considered him to you, Though.";

$cropSentence =  get_words($sentence);

$finalSentence= substr($cropSentence, 0, strrpos($cropSentence, "."));
echo $finalSentence;

它将返回直到最后一次出现（。）;
