You could use something like this:

<pre><code>&lt;?php

$text="Here are some text. The word is inside of the second sentence. And the word is also in this sentence!";
$word = 'word';


function getSentenceByWord($text, $word) {

 $sentences = preg_split('/(\.|\?|\!)(\s)/',$text);
 $matches = array();
 foreach($sentences as $sentence) {

 if (strpos($sentence,$word) !== false) {
 $matches[] = $sentence;
 }

 }

 return $matches;
}

print_r(getSentenceByWord($text, $word));
?&gt;
</code></pre>

returns:

<pre><code>Array
(
 [0] =&gt; The word is inside of the second sentence
 [1] =&gt; And the word is also in this sentence!
)
</code></pre>

Your text:

<pre><code>$txt = "word word word different. different word word word. word word word ending. word word word";
</code></pre>

My word is 'different':

<pre><code>$word = "different";
</code></pre>

Let us do a preg match:

<pre><code>$c=preg_match("/(\.|^)([^\.]*?".$word."[^\.]*(\.|$))/",$txt,$match);
</code></pre>

If it is successful show the second group which holds the sentence:

<pre><code>if($c!==false and count($match) &gt; 0 )
 echo( $match[2]) ;
</code></pre>

This will return the first occurence. If you want all use preg_match_all.

blocks|key|5295774|text|没有正则表达式，只有一个分隔符"."：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|5295775|<?php

Without regular expressions, with a single delimiter, ".":

<pre><code>&lt;?php
$text="Sentence one. Sentence two. Sentence three. Sentence four.";

$word_pos = strpos($text, "Sentence");
$start = strrpos(substr($text, 0, $word_pos), ".");
$end = strpos(substr($text, $word_pos), ".");

$start = $start ? $start + 2 : 0;
$end = $end + $word_pos + 1 - $start;

$sentence = substr($text, $start, $end);

echo $sentence;
</code></pre>

We have some string <code>$text="Here are some text. The word is inside of the second sentence.";</code>and <code>$word="word";</code>

How to get <code>$sentence="The word is inside of the second sentence";</code> - the first sentence that contains <code>" ".$word." "</code>

Of course some assumptions should be made. One of them is that all sentences are finished with <code>".\r\n"</code> or <code>"!\r\n"</code> or <code>". "</code> or <code>"! "</code>.

P.S. We are sure <code>strpos($text," ".$word." ")!==false</code>
