How can PHP developers effectively handle variable naming conventions to improve code readability and maintainability?

Variable naming conventions play a crucial role in improving code readability and maintainability in PHP development. Developers can effectively handle variable naming conventions by following a consistent naming scheme such as camelCase or snake_case, using descriptive names that reflect the purpose of the variable, avoiding abbreviations, and maintaining a clear and logical structure throughout the codebase. 

// Example of using camelCase naming convention for variables
$userName = "John Doe";
$userAge = 30;

// Example of using snake_case naming convention for variables
$user_name = "John Doe";
$user_age = 30;
