例1 ReflectionProperty::setRawValue example

<?php
class Example
{
    public int $age {
        set {
            if ($value <= 0) {
               throw new \InvalidArgumentException();
            }
            $this->age = $value;
        }
    }
}

$example = new Example();

$rClass = new \ReflectionClass(Example::class);
$rProp = $rClass->getProperty('age');

// These would go through the set hook, and throw an exception.
try {
    $example->age = -2;
} catch (InvalidArgumentException) {
    echo "InvalidArgumentException for setting property to -2\n";
}
try {
    $rProp->setValue($example, -2);
} catch (InvalidArgumentException) {
    echo "InvalidArgumentException for using ReflectionProperty::setValue() with -2\n";
}

// But this would set the $age to -2 without error.
$rProp->setRawValue($example, -2);
echo $example->age;
?>

上の例の出力は以下となります。

InvalidArgumentException for setting property to -2
InvalidArgumentException for using ReflectionProperty::setValue() with -2
