What are the potential pitfalls of using dynamic variable names in PHP?

Using dynamic variable names in PHP can make code harder to read and maintain, as the variable names are not explicit and can change during runtime. This can lead to confusion and errors, especially in larger codebases. To avoid this, it is recommended to use associative arrays or objects to store dynamic data instead of creating variable variables. 

// Using associative arrays instead of dynamic variable names
$dynamicData = [
    'name' => 'John',
    'age' => 30
];

echo $dynamicData['name']; // Output: John
