What are the best practices for specifying image dimensions in HTML using PHP?

When specifying image dimensions in HTML using PHP, it is important to provide both the width and height attributes for the image. This helps browsers allocate the necessary space for the image before it is fully loaded, preventing layout shifts and improving performance. To achieve this, you can dynamically retrieve the image dimensions using PHP and output them in the HTML image tag. 

<?php
$image_path = 'image.jpg';
list($width, $height) = getimagesize($image_path);
?>

<img src="<?php echo $image_path; ?>" width="<?php echo $width; ?>" height="<?php echo $height; ?>" alt="Image">
