ReflectionProperty::setRawValue — Sets the value of a property, bypassing a set hook if defined
Sets the value of a property, bypassing a set hook if defined.
objectvalue没有返回值。
If the property is virtual, an Error will be thrown, as there is no raw value to set.
示例 #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;
?>以上示例会输出：
InvalidArgumentException for setting property to -2 InvalidArgumentException for using ReflectionProperty::setValue() with -2 -2
