How can a variable be initialized with a dollar sign preceding it in PHP?

In PHP, variables are typically initialized without a dollar sign preceding them. However, if you want to initialize a variable with a dollar sign included in its name, you can achieve this by using curly braces to enclose the variable name. This allows you to have a dollar sign as part of the variable name while still being able to access and manipulate it in your code.

${'myVariable'} = "Hello, World!";
echo ${'myVariable'}; // Output: Hello, World!
