Late Static
Late static binding is a variant of binding somewhere between static and dynamic binding. Consider the following PHP example:
class A { static $word = "hello"; static function hello {print self::$word;} } class B extends A { static $word = "bye"; } B::hello;In this example, the PHP interpreter binds the function hello to class A, and so the call to B::hello produces the string "hello". If the semantics of "self::$word" had been based on "late static binding", then the result would have been "bye".
Beginning with PHP version 5.3, late static binding is supported . Specifically, if "self::$word" in the above were changed to "static::$word" as shown in the following block, then the result of the call to B::hello would be "bye":
class A { static $word = "hello"; static function hello {print static::$word;} } class B extends A { static $word = "bye"; } B::hello;Read more about this topic: Name Binding
Famous quotes containing the word late:
“Lizzie Borden took an axe
And gave her mother forty whacks;
When she saw what she had done,
She gave her father forty-one.”
—Anonymous. Late 19th century ballad.
The quatrain refers to the famous case of Lizzie Borden, tried for the murder of her father and stepmother on Aug. 4, 1892, in Fall River, Massachusetts. Though she was found innocent, there were many who contested the verdict, occasioning a prodigious output of articles and books, including, most recently, Frank Spiering’s Lizzie (1985)
