<title>Introduction</title>
<para>
<classname>Zend_Server_Reflection</classname> provides a standard mechanism for
performing function and class introspection for use with server classes. It is
based on <acronym>PHP</acronym> 5's Reflection <acronym>API</acronym>, 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.
</para>
<para>
Typically, this functionality will only be used by developers of
server classes for the framework.

<sect2 id="zend.server.reflection.usage">
<title>Usage</title>
<para>
Basic usage is simple:
</para>
<programlisting language="php"><![CDATA[
$class = Zend_Server_Reflection::reflectClass('My_Class');
$function = Zend_Server_Reflection::reflectFunction('my_function');
// Get prototypes
$prototypes = $reflection->getPrototypes();
// Loop through each prototype for the function
foreach ($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()
$reflection->getNamespace();
]]></programlisting>
<para>
<methodname>reflectFunction()</methodname> returns a
<classname>Zend_Server_Reflection_Function</classname> object;
<methodname>reflectClass()</methodname> returns a
<classname>Zend_Server_Reflection_Class</classname> object. Please refer to
the <acronym>API</acronym> documentation to see what methods are available to each.
</para>
