How can the use of the :: operator impact the functionality of variable variables in PHP?

Using the :: operator can impact the functionality of variable variables in PHP because it is used to access static properties or methods of a class, rather than dynamically creating variable variables. To solve this issue, you can use the variable variable syntax $$ to dynamically create variable variables in PHP. 

// Incorrect usage of :: operator
$className = 'Example';
$propertyName = 'value';
echo $className::$propertyName; // This will not work as intended

// Correct way to use variable variables
$className = 'Example';
$propertyName = 'value';
echo ${$className}->{$propertyName}; // This will dynamically access the property value
