How to get certain words from a text with full sentences in PHP?

Question

I want to get some sentences from a text.

Sample text is following,

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.

What I've done so far is I'm able to get 30 words from a large text but at the end, I've got an incomplete sentence and I want to remove such sentence.

Here is the function to get 30 words,

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

I've used above function from the question below

How to select first 10 words of a sentence?

When I pass above text to the function I've got output like this,

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

Here the last sentence is incomplete and I don't want such in my output.

Is there any way to achieve this?

I'm working with PHP and Laravel any kind of help and suggestions are appreciated.

What you're trying to do is pretty complex, I would say - unless you expect some kind of recurrence of the incomplete sentences in the input? Otherwise, I would suggest taking a look at Natural Language Processing software (Spacy is a fast example) - that type of software can help you to dissect these sentences, get tokens and determine if there's enough in a sentence to be a full sentence. — T.

@T.Altena Thanks, for your response. I also thought that but for not so important task implementing NLP is tough one. I think so. I'm looking for some programming tweak that i can achieve quite similar that — Sagar Gautam, Jan 03 '19 at 07:38
You can look at the answers below for Regex approximations of sentence endings. Beware though - if you are going to examine punctuation, abbreviations might throw you off (Prof. X said Y... ), and not all sentences end with a dot ! — T. Altena, Jan 03 '19 at 07:43

This below code may help you.

<?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;
?>

Thanks.

while calling `complete_sentence()`, only resulted `$cropped_data` should be sent again, rather than `$sen` in substr's first parameter, else if `.` exists in a `$sen` after count of 30 words, it will return result up to that point. Resulting finally in more than 30 count of words. Also there will be no benefit of evaluating `$cropped_data` if it is not used proceeding forward. I have made an edit to answer, I hope it gets accepted. — Anant, Jan 03 '19 at 07:46

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;

It will return until the last occurrence of (.);
