ReflectionClass::initializeLazyObject

(PHP 8 >= 8.4.0)

ReflectionClass::initializeLazyObject — Forces initialization of a lazy object

说明

public ReflectionClass::initializeLazyObject(object $object): object

Forces initialization of the specified object. This method has no effect if the object is not lazy or has already been initialized. Otherwise, initialization proceeds as described in the Initialization Sequence.

注意: In most cases, calling this method is unnecessary, as lazy objects initialize themselves automatically when their state is observed or modified.

参数

object: The object to initialize.

返回值

If object is a lazy proxy, returns its real instance. Otherwise, returns object itself.

示例

示例 #1 Basic usage

<?php
class Example
{
    public function __construct(public int $prop) {
    }
}

$reflector = new ReflectionClass(Example::class);

$object = $reflector->newLazyGhost(function ($object) {
    echo "Initializer called\n";
$object->__construct(1);
});

var_dump($object);

$reflector->initializeLazyObject($object);

var_dump($object);
?>

以上示例会输出：

lazy ghost object(Example)#3 (0) {
  ["prop"]=>
  uninitialized(int)
}
Initializer called
object(Example)#3 (1) {
  ["prop"]=>
  int(1)
}
