(PHP 5 >= 5.3.0, PHP 7)
ReflectionProperty::setAccessible — Set property accessibility
$accessible
)Sets a property to be accessible. For example, it may allow protected and private properties to be accessed.
accessible
TRUE to allow accessibility, or FALSE.
No value is returned.
Note that the property will only become accessible using the ReflectionProperty class. The property is still private or protected in the class instances.
<?php
class MyClass {
private $myProperty = true;
}
$class = new ReflectionClass("MyClass");
$property = $class->getProperty("myProperty");
$property->setAccessible(true);
$obj = new MyClass();
echo $property->getValue($obj); // Works
echo $obj->myProperty; // Doesn't work (error)
?>
Have you tried:
<?php
echo "PHP Version: ".phpversion()."\n";
class Foo
{
private $bar = "private";
protected $bar2 = "protected";
public $bar3 = "public";
}
$obj = new Foo;
$arr = (array)$obj;
print_r($arr);
?>
Output:
PHP Version: 5.2.12
Array
(
[Foobar] => private
[*bar2] => protected
[bar3] => public
)
PHP Version: 5.1.6
Array
(
[Foobar] => private
[*bar2] => protected
[bar3] => public
)
If you are using < PHP 5.3 and need to get the private attributes and values, you can use this method:
This is what you are doing:
<?php
$obj_with_privates = new MyObject();
$class = get_class($obj_with_privates);
$vars = get_object_vars($obj_with_privates);
//will not show private attributes
print_r($vars);
$reflection = new ReflectionClass( $class );
$attributes = $reflection->getProperties();
//still no private access!
print_r($attributes);
?>
This is what you should do:
<?php
$obj_with_privates = new MyObject();
$class = get_class( $obj_with_privates );
$reflection = new ReflectionClass( $class );
$abstract = $reflection->getMethods( ReflectionMethod::IS_ABSTRACT );
$priv_attr = $reflection->getProperties( ReflectionProperty::IS_PRIVATE );
$privates = array();
$parent = get_parent_class( $class );
$child = $class;
$constructor = $reflection->getConstructor();
//If the class has abstract methods you need to implement them
$abstr_methods = "";
if(sizeof($abstr_methods))
{
foreach($abstract as $method)
{
$mname = $method->name;
$abstr_methods .= "public function $mname(){return false;}";
}
}
//Convert private attributes to public attributes
if(sizeof($priv_attr))
{
$parseable = unserialize(str_replace("\0$class\0", "\0*\0", serialize($obj)));
foreach($priv_attr as $attribute)
{
$aname = $attribute->name;
$privates[$aname] = $parseable->$aname;
}
}
$temp_child_class = "temp" . str_replace("_", "", "$class");
//You can gain access to protected attributes by extending the target class
$class_def = "
class $temp_child_class extends $class{
$constructor
public function reflect_getmyvars(){
return get_object_vars(\$this);
}
$abstr_methods
}
";
//place class definition in memory
eval($class_def);
//generate object from dynamic class
$tcobj =@ new $temp_child_class;
//call the method we added to the object (to access protected vars)
$vars = $tcobj->reflect_getmyvars();
$attribs = array_merge($vars, $privates);
//will now show private attributes
print_r($attribs);
?>
