Get HTML Tag Attribute Value in PHP

In PHP, you can use various methods to get the value of HTML tag attributes.

One common way is to use the DOM Document class to parse and manipulate HTML documents.

EXAMPLE

// Your HTML content
$html = 'Hello, World!';

// Create a new DOMDocument
$dom = new DOMDocument;

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

// Get the element by tag name (e.g., div)
$elements = $dom->getElementsByTagName('div');

// Loop through the elements
foreach ($elements as $element) {
 // Get the attribute value by attribute name (e.g., id)
 $idAttributeValue = $element->getAttribute('id');

 // Get the attribute value by attribute name (e.g., class)
 $classAttributeValue = $element->getAttribute('class');

 // Output the attribute values
 echo 'ID: ' . $idAttributeValue . '
'; //Output ID: myDiv
 echo 'Class: ' . $classAttributeValue . '
'; //Output Class: example
