How can the issue of individual device compatibility and design consistency be addressed when implementing custom smilies in PHP applications?

Issue: To address the issue of individual device compatibility and design consistency when implementing custom smilies in PHP applications, it is important to use scalable vector graphics (SVG) for the smilies. This will ensure that the smilies look consistent across different devices and screen sizes.
