PropertyAccessor::getValue()

Returns the value at the end of the property path of the object graph.

Example:

use Symfony\Component\PropertyAccess\PropertyAccess;

$propertyAccessor = PropertyAccess::createPropertyAccessor();

echo $propertyAccessor->getValue($object, 'child.name);
// equals echo $object->getChild()->getName();

This method first tries to find a public getter for each property in the path. The name of the getter must be the camel-cased property name prefixed with "get", "is", or "has".

If the getter does not exist, this method tries to find a public property. The value of the property is then returned.

If none of them are found, an exception is thrown.
