What are some alternative methods for displaying and interacting with images in PHP, such as embedding them in HTML or using base64 encoding?

When displaying images in PHP, one alternative method is to embed them directly in HTML using the `<img>` tag. Another method is to use base64 encoding to convert the image data into a string that can be included in the HTML code. This can be useful for smaller images or when you want to avoid additional HTTP requests.

// Embedding image in HTML using <img> tag
echo '<img src="path/to/image.jpg" alt="Image">';

// Using base64 encoding to display image
$imageData = file_get_contents('path/to/image.jpg');
$base64Image = base64_encode($imageData);
echo '<img src="data:image/jpeg;base64,' . $base64Image . '" alt="Image">';
