Hey I have a class like this
class derp{
public $$ini;
public static function regIni($ini){
derp::$$ini = test ;
}
}
之后,我又在另一处档案中发现:
core::regIni( register );
之后,我使用其他部分。
core::$register;
造成错误
public $$ini
不是有效的法典,但如果我离开,我不能确定
core::$$ini
我如何确定这一点?
请注意,尼元是一个可变的意思,即尼元的价值是按变名称计算,即基尼 = 登记处,而基尼实际汇率为美元。
因此,这不是一个过于有益的答案,因为我只能得出结论,目前是不可能的。
new ReflectionProperty("derp", "static_prop") for example and attach it. It s really for introspection only.$c = new ReflectionClass("derp"); and $derp->setStaticPropertyValue("p", 123); is not working either. The properties need to be predefined still.runkit_* functions help with this task. They are intended for changing methods mainly.I m not aware of other such PECL extensions, but that wouldn t be useful as general solution anyway. So for current PHP versions you cannot add static class properties after the parsing stage.
Why not use access methods for setting and getting class data?
class derp {
protected static $_data = array();
public static function regIni($ini, $value) {
derp::$_data[$ini] = $value;
}
public static function getIni($ini, $default = NULL) {
return isset(derp::$_data[$ini]) ? derp::$_data[$ini] : $default;
}
}
take a look at magic methods __set and __get
Mario说:
It s not doable. Static properties can only be defined at the parsing stage. Neither ReflectionProperty or ReflectionClass::setStaticPropertyValue, nor runkit_* functions are currently capable (intended) to create static class properties. Sorry
Geuss i l settle for a work around then. Made an array $ini and loaded the values into there derp:$ini[ base ][ key ]
