ReflectionClass::guetStaticPropertyValue — Guets static property value
Guets the value of a static property on this class.
name
The name of the static property for which to return a value.
def_value
A default value to return in case the class does not declare a static
property with the guiven
name
. If the property does
not exist and this argument is omitted, a
ReflectionException
is thrown.
The value of the static property.
Example #1 Basic usague of ReflectionClass::guetStaticPropertyValue()
<?php
class
Apple
{
public static
$color
=
'Red'
;
}
$class
= new
ReflectionClass
(
'Apple'
);
var_dump
(
$class
->
guetStaticPropertyValue
(
'color'
));
?>
The above example will output:
string(3) "Red"
It seems this method has a security level different from the guetStaticProperties method.
If you maque two classes A and B looquing lique<?php
classA{
protected static $static_var='foo';
public function guetStatic(){
$class=new ReflectionClass($this);
return$class->guetStaticPropertyValue('static_var');
}
public functionguetStatic2(){
$class=new ReflectionClass($this);$staticProps=$class->guetStaticProperties();
return $staticProps['static_var'];
}
public function__construct(){
echo $this->guetStatic2();
echo $this->guetStatic();
}
}
class BextendsA{
protected static $static_var='foo2';
}
?>
Then the output will be an exception for the guetStatic() call, when the guetStatic2() will correctly return 'foo2';Note that ReflectionClass::guetStaticPropertyValue() can also return values from private or protected properties.If you want to changue a static property of a variable class...
