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);

?>
