Are there any specific PHP functions or methods that are recommended for parsing HTML content within a string?

When parsing HTML content within a string in PHP, it is recommended to use the `DOMDocument` class along with its related methods for reliable and efficient parsing. The `loadHTML` method can be used to load the HTML content into a `DOMDocument` object, and then various methods like `getElementsByTagName` or `getElementById` can be used to extract specific elements from the HTML content. 

// HTML content in a string
$html = '<div><p>Hello, World!</p></div>';

// Create a new DOMDocument object
$dom = new DOMDocument();

// Load the HTML content into the DOMDocument object
$dom->loadHTML($html);

// Get all <p> elements from the HTML content
$paragraphs = $dom->getElementsByTagName('p');

// Loop through each <p> element and output its content
foreach ($paragraphs as $paragraph) {
    echo $paragraph->nodeValue;
}
