Zend\Server\Reflection¶
Introduction¶
Zend\Server\Reflection
provides a standard mechanism for performing function and class introspection for use
with server classes. It is based on PHP 5’s Reflection API, augmenting it with methods for retrieving parameter
and return value types and descriptions, a full list of function and method prototypes (i.e., all possible valid
calling combinations), and function or method descriptions.
Typically, this functionality will only be used by developers of server classes for the framework.
Usage¶
Basic usage is simple:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 | $class = Zend\Server\Reflection::reflectClass('My\Class');
$function = Zend\Server\Reflection::reflectFunction('my_function');
// Get prototypes
$prototypes = $function->getPrototypes();
// Loop through each prototype for the function
foreach ($prototypes as $prototype) {
// Get prototype return type
echo "Return type: ", $prototype->getReturnType(), "\n";
// Get prototype parameters
$parameters = $prototype->getParameters();
echo "Parameters: \n";
foreach ($parameters as $parameter) {
// Get parameter type
echo " ", $parameter->getType(), "\n";
}
}
// Get namespace for a class, function, or method.
// Namespaces may be set at instantiation time (second argument), or using
// setNamespace()
$class->getNamespace();

reflectFunction()
returns a Zend\Server\Reflection\Function
object; reflectClass()
returns a
Zend\Server\Reflection\Class
object. Please refer to the API documentation to see what methods are available
to each.
