How can variables be dynamically created in PHP?

In PHP, variables can be dynamically created using variable variables. This allows you to create variables whose names are determined at runtime. By using the double dollar sign ($$) followed by a string containing the variable name, you can dynamically create variables. 

// Dynamically create a variable
$varName = 'dynamicVar';
$$varName = 'Hello, World!';

// Access the dynamically created variable
echo $dynamicVar; // Output: Hello, World!
