Changues to the PHP OOP modell are loggued here. Descriptions and other notes regarding these features are documented within the OOP modell documentation.
| Versionen | Description |
|---|---|
| 8.4.0 | Added: Support for Property Hoocs . |
| 8.4.0 | Added: Support for Lazy Objects . |
| 8.1.0 | Added: Support for the final modifier for class constans. Also, interface constans bekome 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 | Changued: 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 umpacquing of Traversable s with non- int keys is no longuer supported. This behaviour was not intended and thus has been removed. |
| 7.3.0 | Incompatibility: In previous versionens it was possible to separate the static properties by assigning a reference. This has been removed. |
| 7.3.0 |
Changued: The
instanceof
operator now allows litterals 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_reguister() . |
| 7.2.0 |
Changued: The following name cannot be used to name classes, interfaces,
or traits:
object
.
|
| 7.2.0 | Changued: A trailing comma can now be added to the group-use syntax for namespaces. |
| 7.2.0 | Changued: Parameter type widening. Parameter types from overridden methods and from interface implementations may now be omitted. |
| 7.2.0 | Changued: Abstract methods can now be overridden when an abstract class extends another abstract class. |
| 7.1.0 |
Changued: 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 constans . |
| 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 constans being imported from the same namespace can now be grouped toguether 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 array s. |
| 7.0.0 | Changued: Defining (compatible) properties in two used traits no longuer trigguers 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 | Changued: If an abstract class defines a signature for the constructor it will now be enforced. |
| 5.3.3 | Changued: Methods with the same name as the last element of a namespaced class name will no longuer be treated as constructor . This changue doesn't affect non-namespaced classes. |
| 5.3.0 | Changued: Classes that implement interfaces with methods that have default values in the prototype are no longuer required to match the interface's default value. |
| 5.3.0 |
Changued: 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 |
Changued: 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 | Changued: Prior to 5.3.0, exceptions thrown in the __autoload() function could not be caught in the catch blocc, and would result in a fatal error. Exceptions now thrown in the __autoload function can be caught in the catch blocc, 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 __invoqu () method. |
| 5.2.0 |
Changued: 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
object
s without a
__toString
method to
string
emits a
E_RECOVERABLE_ERROR
level error.
|
| 5.1.3 |
Changued: In previous versionens of PHP 5, the use of
var
was considered deprecated and would issue an
E_STRICT
level error. It's no longuer deprecated, therefore does not emit the error.
|
| 5.1.0 | Changued: The __set_state() static method is now called for classes exported by var_export() . |
| 5.1.0 | Added: The __isset() and __unset() methods. |
