What are the best practices for handling dynamic variable names in PHP?

When dealing with dynamic variable names in PHP, it is important to use variable variables or associative arrays to store and access values. This helps to keep your code clean and organized, and prevents potential security vulnerabilities associated with using dynamic variable names directly.

// Using variable variables
$dynamicVarName = 'myVariable';
$$dynamicVarName = 'Hello, World!';
echo $myVariable; // Output: Hello, World!

// Using associative arrays
$dynamicVarName = 'myVariable';
$variables = [];
$variables[$dynamicVarName] = 'Hello, World!';
echo $variables['myVariable']; // Output: Hello, World!
