我想从课文中得到一些句子。

示例文本如下:,

到目前为止,我所做的是我能从一篇大文章中得到30个单词,但最后,我得到了一个不完整的句子,我想删除这样的句子。

下面是获取30个单词的函数,

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

我使用了下面问题中的上述函数

How to select first 10 words of a sentence?

当我将上面的文本传递给函数时,我得到如下输出,

这里的最后一句话是不完整的,我不希望在我的输出这样。

有没有办法做到这一点?

我正在与PHP和Laravel合作,欢迎提供任何帮助和建议。

下面的代码可能对您有所帮助。

<?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;
?>

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;

它将返回到最后一次出现(.);
