[PHP] accessing magic parent set
Is this the only way to access the magic __set from the parent class:
public function __set($columnName, $value)
{
if ($value !== $this->$columnName) {
parent::__set($columnName, $value);
}
}
I would have liked to work this way:
public function __set($columnName, $value)
{
if ($value !== $this->$columnName) {
parent::$columnName = $value;
}
}
And another question.
There is a self, a static and a parent
Why is it only $this and not a $parent too?
Re: [PHP] code quest - ECHO?!?
They are almost identical. Echo supports multiple parameters like "echo $a, $b;" print is 20% slower than echo (by some tests). "echo" is shorter than "print" so it's easy to write. In fact it's all a matter of taste. The same reason we user die instead of exit. Alex On Sun, Dec 12, 2010 at 6:23 PM, Kirk Bailey wrote: > Groovy; they appear to be identical in all but name.

Re: [PHP] ORM doctrine
Doctrine is mature and well I've seen it plenty of times companies using it. Of course it handles multi table joins but I think it's main purpose is not related to users writing joins... It's an ORM, you just read and write objects. Caching is something that must be there and you can read more on wiki: http://en.wikipedia.org/wiki/Doctrine_%28PHP%29 Alex On Thu, Dec 9, 2010 at 5:02 AM, Tommy Pham wrote: > Hi, > > Has anyone used doctrine before?

Re: [PHP] new keyword combined with other things...
I know how to do it in other ways.
I was just wondering why the simple new Object() -> method won't work. new
operator has precedence over...
That must be the problem. -> is not an operator. Is not in this list:
http://php.net/manual/en/language.operators.precedence.php
That must be done. -> should be an operator!

[PHP] new keyword combined with other things...
In many other languages this will work: *$result = new Object() -> method();* But in php, it fails at parsing. I've tried with parenthesis around new but nothing. Anyhow, as I saw later, *new* operator has precedence over others so this couldn't be a solution. I know a static function can be defined and the above statement can transform into *$result = Object::getNewInstance() -> method()* but is there any way to write it directly? and if not, why isn't this implemented yet and when will it be? best regards, Patranescu Alexandru
