How can the greedy nature of regular expressions impact parsing HTML content in PHP?

The greedy nature of regular expressions can cause issues when parsing HTML content in PHP because it may match more content than intended, leading to incorrect results. To solve this issue, you can use the non-greedy modifier '?' to make the regular expression match as little as possible.

$html = &#039;&lt;div&gt;&lt;p&gt;Hello, &lt;strong&gt;world&lt;/strong&gt;&lt;/p&gt;&lt;/div&gt;&#039;;
preg_match(&#039;/&lt;div&gt;(.*?)&lt;\/div&gt;/&#039;, $html, $matches);
echo $matches[1]; // Output: &lt;p&gt;Hello, &lt;strong&gt;world&lt;/strong&gt;&lt;/p&gt;
