What are the potential pitfalls of using boldface formatting in PHP code?

Using boldface formatting in PHP code can lead to confusion and make the code harder to read and maintain. It is generally not a standard practice in PHP coding conventions. To improve code readability, it is recommended to use consistent indentation, proper naming conventions, and comments to explain the purpose of the code.

// Example of properly formatted PHP code
<?php

// Define a variable with a meaningful name
$age = 25;

// Check if the age is greater than 18
if ($age > 18) {
    echo "You are an adult.";
} else {
    echo "You are a minor.";
}

?>
