I have to find title but print value how?

Question

My code is given below:-

$text = "<div class='title'>Title</div><div class='content'>This is title</div>";

$words = array('Title');

$words = join("|", $words);

$matches = array();

if ( preg_match('/' . $words . '/i', $text, $matches) ){
    echo "Words matched: <br/>";
    print_r($matches);
}

else{
    echo "Not match";
}

The problem is that in above code I am finding title but i don't want to print title; I want to print this: "This is title" and I am not understanding how I can print this by finding title.

Because title is like keyword that will not change but value which i want to print it is dynamic value and it will change every time, that's why i cannot finding value of title. So how can i do it?

Don't use regex for parsing HTML. Use a DOM Parser instead. In this case, you can use an XPath expression to get the element by class name:

$text = "<div class='title'>Title</div>
<div class='content'>This is title</div>";
$dom = new DOMDocument;
$dom->loadHTML($text);
$xpath = new DOMXPath($dom);
$title = $xpath->query('//*[@class="content"]')->item(0)->nodeValue;

Output:

This is title

This should get you started. If the title is in a different position, you can modify the expression accordingly to retrieve it.
