What are common issues with PHP code highlighting and how can they be resolved?

One common issue with PHP code highlighting is when the syntax highlighting does not work properly due to incorrect configuration or missing plugins in code editors. This can make it difficult to identify and debug errors in the code. To resolve this issue, make sure to install the necessary plugins or extensions for PHP syntax highlighting in your code editor.

// Example PHP code snippet with correct syntax highlighting configuration
<?php
echo "Hello, World!";
?>
