How to get content from first html tag using class name

[jasonc]

<h1 class="property-title">Title 1</h1>
<h1 class="property-title">Title 2</h1>

How would I get just the first h1 using the class name from the DOM that it placed in a string?

PHP’s inbuilt DOMDocument is useful for parsing HTML:

<?php

function getTextBetweenTags($htmlContent, $tagName)
{
    $d = new DOMDocument();
    $d->loadHTML($htmlContent);

    $output = [];
    foreach($d->getElementsByTagName($tagName) as $item){
        $output[] = $item->textContent;
    }

    return $output;
}

$content = <<<EOT
<h1 class="property-title">Title 1</h1>
<h1 class="property-title">Title 2</h1>
EOT;

$h1Content = getTextBetweenTags($content, 'h1');

echo reset($h1Content), PHP_EOL;
