What are some best practices for naming variables and maintaining code readability in PHP scripts?

When naming variables in PHP scripts, it is important to use descriptive names that clearly indicate the purpose of the variable. This helps improve code readability and maintainability. Additionally, following a consistent naming convention, such as camelCase or snake_case, can make the code easier to understand for other developers. Avoid using abbreviations or overly generic names that may cause confusion.

// Example of using descriptive variable names in PHP
$userName = "John Doe";
$userAge = 30;
$userEmail = "johndoe@example.com";
