如何从PHP中包含完整句子的文本中获取特定的单词？
如何从PHP中包含完整句子的文本中获取特定的单词？
提问于 2019-01-03 06:32:57
我想从一篇文章中得到一些句子。
示例文本如下，
鹰头狮低声打断了声音。“一点也不，”渡渡鸟指着树林里的嘈杂声说。(她把他想给你听了，Though.Gryphon低声打断了他的话。)“一点也不，”渡渡鸟指着树林里的嘈杂声说。(她把他想给你听了，Though.Gryphon低声打断了他的话。)“一点也不，”渡渡鸟说，指着树林里混乱的喧闹声
到目前为止，我所做的是能够从一个大的文本中得到30个单词，但最后，我有一个不完整的句子，我想删除这样的句子。
这是得到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];
}我在下面的问题中使用了上述函数
How to select first 10 words of a sentence?
当我把上面的文字传递给函数时，我得到了这样的输出，
鹰头狮低声打断了声音。“一点也不，”渡渡鸟指着树林里混乱的吵闹声说。(她把他当成你了，Though.Gryphon打断了他的话)。
在这里，最后一句是不完整的，我不希望在我的输出这样。
有办法做到这一点吗？
我正在与PHP和Laravel合作，任何类型的帮助和建议都很感谢。

下面的代码可能对您有帮助。
<?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;它将返回到(.)的最后一次出现；
鹰头狮低声打断了声音。“一点也不，”渡渡鸟说，指着树林里混乱的喧闹声
