(PHP 5, PHP 7, PHP 8)
ReflectionProperty::isDefault — Checks if property is a default property
Checks whether the property was declared at compile-time, or whether the property was dynamically declared at run-time.
此函數沒(méi)有參數。
true if the property was declared at compile-time, or false if
it was created at run-time.
示例 #1 ReflectionProperty::isDefault() example
<?php
class Foo {
public $bar;
}
$o = new Foo();
$o->bar = 42;
$o->baz = 42;
$ro = new ReflectionObject($o);
var_dump($ro->getProperty('bar')->isDefault());
var_dump($ro->getProperty('baz')->isDefault());
?>
以上例程會(huì )輸出：
bool(true) bool(false)
