Example #1 ReflectionProperty::__construct() example
<?php
class String
{
public $length = 5;
}
// Create an instance of the ReflectionProperty class
$prop = new ReflectionProperty('String', 'length');
// Print out basic information
printf(
"===> The%s%s%s%s property '%s' (which was %s)\n" .
" having the modifiers %s\n",
$prop->isPublic() ? ' public' : '',
$prop->isPrivate() ? ' private' : '',
$prop->isProtected() ? ' protected' : '',
$prop->isStatic() ? ' static' : '',
$prop->getName(),
$prop->isDefault() ? 'declared at compile-time' : 'created at run-time',
var_export(Reflection::getModifierNames($prop->getModifiers()), 1)
);
// Create an instance of String
$obj= new String();
// Get current value
printf("---> Value is: ");
var_dump($prop->getValue($obj));
// Change value
$prop->setValue($obj, 10);
printf("---> Setting value to 10, new value is: ");
var_dump($prop->getValue($obj));
// Dump object
var_dump($obj);
?>
El resultado del ejemplo sería algo similar a:
===> The public property 'length' (which was declared at compile-time)
having the modifiers array (
0 => 'public',
)
---> Value is: int(5)
---> Setting value to 10, new value is: int(10)
object(String)#2 (1) {
["length"]=>
int(10)
}
Example #2 Getting value from private and protected properties using ReflectionProperty class
<?php
class Foo {
public $x = 1;
protected $y = 2;
private $z = 3;
}
$obj = new Foo;
$prop = new ReflectionProperty('Foo', 'y');
$prop->setAccessible(true); /* As of PHP 5.3.0 */
var_dump($prop->getValue($obj)); // int(2)
$prop = new ReflectionProperty('Foo', 'z');
$prop->setAccessible(true); /* As of PHP 5.3.0 */
var_dump($prop->getValue($obj)); // int(2)
?>
El resultado del ejemplo sería algo similar a:
int(2) int(3)
