why this is updated (php 5.3.0)?
OOP Changelog
Changes to the PHP OOP model are logged here. Descriptions and other notes regarding these features are documented within the OOP model documentation.
| Version | Description |
|---|---|
| 8.1.0 | Added: Support for the final modifier for class constants. Also, interface constants become overridable by default. |
| 8.0.0 | Added: Support for the nullsafe operator ?-> to access properties and methods on objects that may be null. |
| 7.4.0 | Changed: It is now possible to throw exception within __toString(). |
| 7.4.0 | Added: Support for limited return type covariance and argument type contravariance. Full variance support is only available if autoloading is used. Inside a single file only non-cyclic type references are possible. |
| 7.4.0 | Added: It is now possible to type class properties. |
| 7.3.0 | Incompatibility: Argument unpacking of Traversables with non-int keys is no longer supported. This behaviour was not intended and thus has been removed. |
| 7.3.0 | Incompatibility: In previous versions it was possible to separate the static properties by assigning a reference. This has been removed. |
| 7.3.0 |
Changed: The instanceof
operator now allows literals as the first operand, in which case the
result is always false.
|
| 7.2.0 | Deprecated: The __autoload() method has been deprecated in favour of spl_autoload_register(). |
| 7.2.0 |
Changed: The following name cannot be used to name classes, interfaces,
or traits: object.
|
| 7.2.0 | Changed: A trailing comma can now be added to the group-use syntax for namespaces. |
| 7.2.0 | Changed: Parameter type widening. Parameter types from overridden methods and from interface implementations may now be omitted. |
| 7.2.0 | Changed: Abstract methods can now be overridden when an abstract class extends another abstract class. |
| 7.1.0 |
Changed: The following names cannot be used to name classes, interfaces,
or traits: void and iterable.
|
| 7.1.0 | Added: It is now possible to specify the visibility of class constants. |
| 7.0.0 | Deprecated: Static calls to methods that are not declared static. |
| 7.0.0 | Deprecated: PHP 4 style constructor. I.e. methods that have the same name as the class they are defined in. |
| 7.0.0 | Added: Group use declaration: classes, functions and constants being imported from the same namespace can now be grouped together in a single use statement. |
| 7.0.0 |
Added: Support for
anonymous classes
has been added via new class.
|
| 7.0.0 | Incompatibility: Iterating over a non-Traversable object will now have the same behaviour as iterating over by-reference arrays. |
| 7.0.0 | Changed: Defining (compatible) properties in two used traits no longer triggers an error. |
| 5.6.0 | Added: The __debugInfo() method. |
| 5.5.0 | Added: The ::class magic constant. |
| 5.5.0 | Added: finally to handle exceptions. |
| 5.4.0 | Added: traits. |
| 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: An E_WARNING level error is issued if
the magic overloading
methods are declared static.
It also enforces the public visibility requirement.
|
| 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. Exceptions now thrown in the __autoload function can be caught in the catch block, with one provison. If throwing a custom exception, then the custom exception class must be available. The __autoload function may be used recursively to autoload the custom exception class. |
| 5.3.0 | Added: The __callStatic method. |
| 5.3.0 | Added: heredoc and nowdoc support for class const and property definitions. Note: heredoc values must follow the same rules as double-quoted strings, (e.g. no variables within). |
| 5.3.0 | Added: Late Static Bindings. |
| 5.3.0 | Added: The __invoke() method. |
| 5.2.0 |
Changed: The __toString()
method was only called when it was directly combined with
echo or print.
But now, it is called in any string context (e.g. in
printf() with %s modifier) but not
in other types contexts (e.g. with %d modifier).
As of PHP 5.2.0, converting objects without a
__toString method to string
emits a E_RECOVERABLE_ERROR level error.
|
| 5.1.3 |
Changed: In previous versions of PHP 5, the use of var
was considered deprecated and would issue an E_STRICT
level error. It's no longer deprecated, therefore does not emit the error.
|
| 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. |
