Many examples exist within the Reflection documentation, typically within the __construct documentation for each class.
Example #1 Reflection Example from Shell (a Terminal)
$ php --rf strlen $ php --rc finfo $ php --re json $ php --ri dom
The above example will output something similar to:
Function [ <internal:Core> function strlen ] { - Parameters [1] { Parameter #0 [ <required> $str ] } } Class [ <internal:fileinfo> class finfo ] { - Constants [0] { } - Static properties [0] { } - Static methods [0] { } - Properties [0] { } - Methods [4] { Method [ <internal:fileinfo, ctor> public method finfo ] { - Parameters [2] { Parameter #0 [ <optional> $options ] Parameter #1 [ <optional> $arg ] } } Method [ <internal:fileinfo> public method set_flags ] { - Parameters [1] { Parameter #0 [ <required> $options ] } } Method [ <internal:fileinfo> public method file ] { - Parameters [3] { Parameter #0 [ <required> $filename ] Parameter #1 [ <optional> $options ] Parameter #2 [ <optional> $context ] } } Method [ <internal:fileinfo> public method buffer ] { - Parameters [3] { Parameter #0 [ <required> $string ] Parameter #1 [ <optional> $options ] Parameter #2 [ <optional> $context ] } } } } Extension [ <persistent> extension #23 json version 1.2.1 ] { - Constants [10] { Constant [ integer JSON_HEX_TAG ] { 1 } Constant [ integer JSON_HEX_AMP ] { 2 } Constant [ integer JSON_HEX_APOS ] { 4 } Constant [ integer JSON_HEX_QUOT ] { 8 } Constant [ integer JSON_FORCE_OBJECT ] { 16 } Constant [ integer JSON_ERROR_NONE ] { 0 } Constant [ integer JSON_ERROR_DEPTH ] { 1 } Constant [ integer JSON_ERROR_STATE_MISMATCH ] { 2 } Constant [ integer JSON_ERROR_CTRL_CHAR ] { 3 } Constant [ integer JSON_ERROR_SYNTAX ] { 4 } } - Functions { Function [ <internal:json> function json_encode ] { - Parameters [2] { Parameter #0 [ <required> $value ] Parameter #1 [ <optional> $options ] } } Function [ <internal:json> function json_decode ] { - Parameters [3] { Parameter #0 [ <required> $json ] Parameter #1 [ <optional> $assoc ] Parameter #2 [ <optional> $depth ] } } Function [ <internal:json> function json_last_error ] { - Parameters [0] { } } } } dom DOM/XML => enabled DOM/XML API Version => 20031129 libxml Version => 2.7.3 HTML Support => enabled XPath Support => enabled XPointer Support => enabled Schema Support => enabled RelaxNG Support => enabled
