Practical Guide to Generating and Parsing HTML Tags with PHP

Examples of Generating Common HTML Tags with PHP

In modern web development, PHP is widely used as a server-side scripting language to dynamically generate HTML content. Developers can output various HTML tags with simple code to enhance the interactivity and flexibility of webpages.

Generating Paragraph Tags

echo "This is a paragraph.";

Generating Link Tags

echo "Click here to visit the example site.";

Generating List Tags

echo ""; echo "First item"; echo "Second item"; echo "Third item"; echo "";

Parsing Generated HTML Tags with PHP

After generating HTML tags, parsing these tags is a crucial step in handling dynamic content. PHP's built-in DOMDocument class can effectively parse and manipulate HTML structures, making it easy to extract and modify node content.

Basic Usage of DOMDocument

$html = "Parse this paragraph.";$dom = new DOMDocument();@ $dom->loadHTML($html);$paragraphs = $dom->getElementsByTagName('p');foreach ($paragraphs as $para) {    echo $para->nodeValue;}
