Question

How would I use PHP’s preg_replace() to return only the value inside the <h1> in the following string (it’s HTML text loaded in a variable called $html):

<h1>I'm Header</h1>

<p>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Pellentesque tincidunt porttitor magna, quis molestie augue sagittis quis.</p>

<p>Pellentesque tincidunt porttitor magna, quis molestie augue sagittis quis. Lorem ipsum dolor sit amet, consectetur adipiscing elit.</p>

I’ve tried this: preg_replace('#<h1>([.*])</h1>.*#', '$1', $html), but to no avail. Am I regex-ing this correctly? And is there a better PHP function that I should be using instead of preg_replace?

Here is how you do it using preg_replace:

$header = preg_replace('/<h1>(.*)<\/h1>.*/iU', '$1', $html);

You can also use preg_match:

$matches = array();
preg_match('/<h1>(.*)</h1>.*/iU', $html, $matches);
print_r($matches);
