Afternoon all,
I'd love to get some votes from my fellow developers on the following,
and indeed some opinions (especially from those who disagree).
Recently I've been running in to a lot of frustrations with PHP when
dealing with Classes and Objects. Personally I strongly feel that these
need added in to PHP 6, for multiple reasons.
I don't think the scope of this discussion covers the syntax of any
implementation, just if it needs implemented or not.
a: Optional Static Typing
I'm finding an ever increasingly need to be able to staticly type
properties, parameters, return types etc (in classes) I know there is
type hinting but it's just not enough to do what one needs. Additionally
support for staticly typing primatives. Here's an example:
<?php
class Example {
private ClassName $obj; // class typed property
public bool $primativeBool; // primative typed property
// typed returns
public function getObj() ClassName {
return $this->obj;
}
// already implemented
public function setObj(ClassName $obj) {
$this->obj = $obj;
}
// privative type hint (not implemented)
public function setPrimativeBool(bool $primativeBool) {
$this->primativeBool = $primativeBool;
}
public function someMethod() {
// also for variables
VariableType $variable = new VariableType();
}
}
?>
b: Object superclass
A base class type which all objects automagically extend, with (if
nothing else) a unique id / hashcode for each object (much like the Java
Object class). Failing this some form of function to get a unique
reference string for any variable. Example
<?php
$someClassInstance = new SomeClass();
// method on all objects that returns a unique
// id for that object
$objectId = $someClassInstance->hashCode();
// or by a function
$objectId = get_hashcode($someClassInstance);
// and for variables
$aString = 'some string';
$stringId = get_hashcode($aString);
?>
c: Method overloading
TBH it's something I could live without, whereas a/b aren't, but it
would be an ideal addition to php?
<?php
class Example {
public function someMethod(ClassType $arg0) {
}
public function someMethod(ClassType $arg0, bool $arg1) {
}
}
?>
Thoughts, Opinions, Votes? would love to hear from you guys on this
Regards!
