What are the best practices for preventing undeclared variable errors when using dynamic content inclusion in PHP?

When including dynamic content in PHP, it is important to prevent undeclared variable errors by checking if the variables are set before using them. This can be done using the isset() function to ensure that the variables exist before trying to access them. By implementing this check, you can avoid errors and ensure that your code runs smoothly. 

if(isset($dynamicVariable)) {
    // Include dynamic content using $dynamicVariable
    include $dynamicVariable;
} else {
    echo "Error: Dynamic variable is not set.";
}
