ReflectionProperty::getDefaultValue
(PHP 8)
ReflectionProperty::getDefaultValue — Returns the default value declared for a property
Description
Gets the implicit or explicitly declared default value for a property.
Parameters
This function has no parameters.
Return Values
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 ReflectionProperty::hasDefaultValue() to detect the difference.
Examples
Example #1 ReflectionProperty::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());
?>
The above example will output:
int(1) NULL int(0)
