extract sentences with specific words

How would I make this regex also check for a specific term / string?

 

 

preg_match_all('/(?<=[.?!]|^).*?(?=([.?!])\s{0,3}[A-Z]|$)/s',$content,$matches);
echo "<pre>";
for($i=0;$i<count($matches[0]);$i++)
$result[] = trim($matches[0][$i]).$matches[1][$i];
print_r($result);
}

preg_match_all('/(?<=[.?!]|^).*?(?=([.?!])\s{0,3}[A-Z]|$)/s',$content,$matches);

As in using brackets to specify a string to check is in the sentence

('.$search.')

So, just to make it clear:

-Getting only sentences

-And also making sure the sentences contain a specific string ($search)

 

 

preg_match_all('/(?<=[.?!]|^).*?(?=([.?!])\s{0,3}   == I would assume the ($search) goes somewhere here in the middle ==   [A-Z]|$)/s',$content,$matches);

Extracting "sentences" is complex and imperfect enough. It would be better to leave your current regex alone and do a 2nd filter.

 

// do the sentence matching
preg_match_all('/(?<=[.?!]|^).*?(?=([.?!])\s{0,3}[A-Z]|$)/s',$content,$matches);
// wrap search term in preg_quote if you are accepting arbitrary data, so as to escape special regex chars
$search = preg_quote('foobar','~'); 
// return sentences that have $search in it. remove the "i" modifier if you want it to be case-sensitive
$sentences = preg_grep('~'.$search.'~i',$matches[0]);
