How can PHP developers leverage tools like syntax highlighting editors to improve code quality and readability?

PHP developers can leverage syntax highlighting editors to improve code quality and readability by enabling them to easily identify different elements of the code such as variables, functions, and keywords. This makes the code easier to read and understand, reducing the chances of errors and improving overall code quality.

<?php

// Example code snippet with syntax highlighting
$variable = "Hello, World!";

function displayMessage($message) {
    echo $message;
}

displayMessage($variable);

?>
