How can one dynamically change variable names in PHP based on other variables?

To dynamically change variable names in PHP based on other variables, you can use variable variables. This means using the value of one variable as the name of another variable. This can be achieved by enclosing the variable name in curly braces and using the double dollar sign notation. Example:

$base_variable = 'dynamic';
$$base_variable = 'Hello, World!';
echo $dynamic; // Output: Hello, World!
