How can one avoid using variable variables in PHP when dealing with dynamic content?

Variable variables in PHP can lead to confusion and make code harder to read and maintain. Instead of using variable variables, it's better to use arrays or objects to store dynamic content. This way, you can access the data using keys or properties, which is more explicit and easier to understand. 

// Avoid using variable variables by using arrays or objects
$dynamicContent = [
    'name' => 'John',
    'age' => 30,
];

echo $dynamicContent['name']; // Output: John
echo $dynamicContent['age']; // Output: 30
