static keyword in php 5

Static varriables and constants are accessed by the scope resolution operator. But it will not show any errors. If you set the error level to E_STRICT, then it will show an error.


Question:

Consider the following PHP 4 code snippet:

value = $value;
}

function doSomething($myClass) {
$myClass->setValue(10);
}
}

$myClass = new MyClass();
MyClass::doSomething($myClass);
?>
In PHP 5, will this code change behavior? Why or why not?

Answer:

1. No, Not unless E_STRICT is enabled
2. Yes, you have to declare doSomething() static now
3. Yes, objects are now reference based
4. No, it will function exactly the same
