from 

 $content = "The International Journal of Nursing published a

disorders. In this study, music was played when they ...";

and somtimes the content can be

 $content = "The International Journal of Nursing published a

You can use this regex (https://regex101.com/r/elRsha/2):

$line = "study of 557 adults suffering from sleep";

$content = "The International Journal of Nursing published a
<b>study of 557 adults suffering</b>
<br>
<b>from sleep</b>
disorders. In this study, music was played when they ...";

$line = implode('(?:[\n\s\t]*(?:<.+>)*[\n\s\t]*)*', explode(' ', $line));

preg_match("#($line)#is",$content,$match);
print_r($match);

First remove HTML tag from string using strip_tags function and then remove newlines from string.

$line = "study of 557 adults suffering from sleep";

$content = "The International Journal of Nursing published a
<b>study of 557 adults suffering</b>
<br>
<b>from sleep</b>
disorders. In this study, music was played when they ...";

echo preg_match("#$line#is",trim(preg_replace('/\s+/', ' ', strip_tags($content))),$match);

Like this? https://regex101.com/r/PDehGB/2 

$pattern = '/<b>study.*?of.*?557.*?adults.*?suffering.*?from.*?sleep<\/b>/ms';

With this pattern it will take care of any new lines and still keep the $line.

You can explode the $line on " " and build the pattern with implode(".*?", $arr)
