How can variable names be dynamically created using other variable names in PHP?

To dynamically create variable names using other variable names in PHP, you can use variable variables. Variable variables allow you to create variable names dynamically by using the value of a variable as the name of another variable. This can be achieved by enclosing the variable name in curly braces and using double dollar signs. 

$firstVariable = 'hello';
${$firstVariable . 'World'} = 'Dynamic Variable Created!';
echo $helloWorld; // Output: Dynamic Variable Created!
