> 5.5.0 Added: finally to handle exceptions.
Why it's mentioned here? There is separate section about Exceptions.
Changes to the PHP 5 OOP model are logged here. Descriptions and other notes regarding these features are documented within the OOP 5 documentation.
|5.5.0||Added: finally to handle exceptions.|
|5.4.0||Changed: If an abstract class defines a signature for the constructor it will now be enforced.|
|5.3.3||Changed: Methods with the same name as the last element of a namespaced class name will no longer be treated as constructor. This change doesn't affect non-namespaced classes.|
|5.3.0||Changed: Classes that implement interfaces with methods that have default values in the prototype are no longer required to match the interface's default value.|
|5.3.0||Changed: It's now possible to reference the class using a variable (e.g., echo $classname::constant;). The variable's value can not be a keyword (e.g., self, parent or static).|
|5.3.0||Changed: Prior to 5.3.0, exceptions thrown in the __autoload() function could not be caught in the catch block, and would result in a fatal error.

The __autoload function may be used recursively to autoload the custom exception class.|

echo or print.
But now, it is called in any string context (e.g. in
printf() with %s modifier) but not

Since PHP 5.2.0, converting objects without a __toString
method to string emits a
Changed: In previous versions of PHP 5, the use of var
was considered deprecated and would issue an
|5.1.0||Changed: The __set_state() static method is now called for classes exported by var_export().|
|5.1.0||Added: The __isset() and __unset() methods.|
