How can PHP variables be named to maintain clarity and avoid confusion in code?

To maintain clarity and avoid confusion in code, PHP variables should be named descriptively and consistently following a naming convention such as camelCase or snake_case. Avoid using vague or overly generic names that could be easily confused with other variables in the code. Additionally, consider using prefixes or namespaces to indicate the scope or purpose of the variable. 

// Example of clear and descriptive variable naming
$userName = "JohnDoe";
$userAge = 25;
$userEmail = "johndoe@example.com";
