How can the ReflectionClass class be used to report information about a class in PHP?

To report information about a class in PHP, you can use the ReflectionClass class. This class provides a way to retrieve information about a class, such as its methods, properties, and parent class. By creating an instance of ReflectionClass with the class name as a parameter, you can then use its methods to access and display information about the class. 

// Create a ReflectionClass instance for the desired class
$reflection = new ReflectionClass('ClassName');

// Get class name
echo 'Class Name: ' . $reflection->getName() . PHP_EOL;

// Get class methods
$methods = $reflection->getMethods();
echo 'Class Methods: ' . PHP_EOL;
foreach ($methods as $method) {
    echo $method->getName() . PHP_EOL;
}

// Get class properties
$properties = $reflection->getProperties();
echo 'Class Properties: ' . PHP_EOL;
foreach ($properties as $property) {
    echo $property->getName() . PHP_EOL;
}

// Get parent class
$parentClass = $reflection->getParentClass();
if ($parentClass) {
    echo 'Parent Class: ' . $parentClass->getName() . PHP_EOL;
} else {
    echo 'No Parent Class' . PHP_EOL;
}
