What are some best practices for optimizing the performance of buttons with images in PHP?

When using buttons with images in PHP, it is important to optimize their performance by properly caching the images and using efficient code to render them. One best practice is to store the image paths in variables to avoid repetitive calls to the filesystem. Additionally, using CSS sprites or lazy loading techniques can help reduce the number of HTTP requests and improve loading times. 

<?php
// Store image paths in variables
$imagePath = 'path/to/image.jpg';

// Output button with image
echo '<button><img src="' . $imagePath . '" alt="Button Image"></button>';
?>
