Are there any best practices for naming variables in PHP to avoid conflicts?

To avoid conflicts when naming variables in PHP, it is best practice to use descriptive and unique names that clearly reflect the purpose of the variable. Additionally, prefixing variables with a unique identifier related to the context can help differentiate them from variables with similar names in other parts of the code. Finally, following a consistent naming convention, such as camelCase or snake_case, can also help maintain clarity and organization in your code.

// Example of using unique prefixes and descriptive names to avoid conflicts
$userName = "John Doe";
$userEmail = "john.doe@example.com";
$userAge = 30;
