Take a part of a big text

Let's say we have a string ($text) 

I will help you out, if <b>you see this message and never forget</b> blah blah blah

I want to take text from "<b>" to "</b>" into a new string($text2) How can this be done?

I appreciate any help I can get. Thanks!

Edit: I want to take a code like this.

Use this bad mofo: https://www.php.net/domdocument

$dom = new DOMDocument();
$dom->loadHTML($text);

$xpath = new DOMXpath($dom);
$nodes = $xpath->query('//b');

Here you can either loop through each one, or if you know there is only one, just grab the value.

$text1 = $nodes->item(0)->nodeValue;

If you only wish the first match and do not want to match something like <b class=">, the following will work:

UPDATED for comment:

$text = "I will help you out, if <b>you see this message and never forget</b> blah blah blah";
$matches = array();
preg_match('@<b>.*?</b>@s', $text, $matches);
if ($matches) {
    $text2 = $matches[0];
    // Do something with $text2
}
else {
    // The string wasn't found, so do something else.
}

But for something more complex, you really should parse it as DOM per Marc B.'s comment.

strip_tags($text, '<b>');

will extract only the parts of the string between <b> </b>

If it is the behavior you look for.
