ReflectionFunction is a class in PHP which helps in analyzing functions and their structure through code. It allows us to access the name, parameter list, return type, and other metadata about the function. This class is part of the Reflection package in PHP.

Example 1: Get the details of a function using ReflectionFunction:

function sum($a, $b) {
  return $a + $b;
}

$reflectionFunc = new \ReflectionFunction('sum');
echo $reflectionFunc->getName() . PHP_EOL;  // Output: sum
$parameters = $reflectionFunc->getParameters();
foreach($parameters as $param) {
    echo $param->getName() . "\n";
}

In this example, we are defining a function called `sum` and using the ReflectionFunction class to get information about it. We are getting the name of the function and its parameters.

Example 2: Invoke a function using ReflectionFunction:

function sum($a, $b) {
  return $a + $b;
}

$reflectionFunc = new \ReflectionFunction('sum');
$args = [2, 3];
$result = $reflectionFunc->invokeArgs($args);
echo $result;  // Output: 5

In this example, we are using the `invokeArgs` method of ReflectionFunction to execute the `sum` function with arguments 2 and 3. The method returns the result which is then printed using `echo`. These are simple examples demonstrating the use of ReflectionFunction in PHP. The Reflection package is part of the PHP Core, so no external package/library is required to use it.
