How can dynamic variable names be handled in PHP functions?

Dynamic variable names can be handled in PHP functions by using variable variables. This means that you can create variable names dynamically by concatenating strings or using variables as part of the variable name. This can be useful when you need to dynamically access or set variables within a function. 

function setDynamicVariable($name, $value) {
    ${$name} = $value;
}

$name = "dynamicVar";
$value = "Hello, World!";
setDynamicVariable($name, $value);

echo $dynamicVar; // Outputs: Hello, World!
