ReflectionProperty::getDefaultValue — Returns the default value declared for a property
Gets the implicit or explicitly declared default value for a property.
Diese Funktion besitzt keine Parameter.
The default value if the property has any default value (including NULL
).
If there is no default value, then NULL
is returned. It is not possible to differentiate
between a NULL
default value and an unitialized typed property.
Use ReflectionClass::hasDefaultValue() to detect the difference.
Beispiel #1 ReflectionClass::getDefaultValue() example
<?php
class Foo {
public $bar = 1;
public ?int $baz;
public int $boing = 0;
}
$ro = new ReflectionClass(Foo::class);
var_dump($ro->getProperty('bar')->getDefaultValue());
var_dump($ro->getProperty('baz')->getDefaultValue());
var_dump($ro->getProperty('boing')->getDefaultValue());
?>
Das oben gezeigte Beispiel erzeugt folgende Ausgabe:
int(1) NULL int(0)
