What are the best practices for naming variables and files in PHP to enhance code readability?

When naming variables and files in PHP, it is important to use descriptive and meaningful names that accurately reflect the purpose of the variable or file. This helps improve code readability and makes it easier for other developers to understand the code. Avoid using vague or generic names, and instead opt for names that clearly convey the intended use of the variable or file. 

// Bad variable naming
$a = 10;
$b = "Hello";

// Good variable naming
$age = 10;
$message = "Hello";
