代码解释得更好：
class Class{
$var = 0;
function getvar()
echo $this->var;
}
}
$inst1 = new Class();
// I want to change $var here to 5
$inst2 = new Class();
echo $inst2->getvar(); // should be 5
可能吗
静态的.

class MyClass {
public static $var = 0;
function setVar($value) {
self::$var = $value;
}
function getVar() {
return self::$var;
}
}
echo MyClass::$var;
MyClass::setVar(1);
echo MyClass::getVar(); //Outputs 1
