Class to access ALL properties of a __PHP_Incomplete_Class
PLEASE NOTE: This is a proof of concept and not ment to be used in production software.
- You have an object serialized and stored to e.g. the database.
- Time is passing by and the underlying class has been modified, moved or deleted.
- You read the serealized object from your storage and receive a
__PHP_Incomplete_Class
object. - You want to read the object's properties, even those which are private.
- PHP does not provide a convenient way to read private properties from such an object.
ReflectionClass
does not publish any of the properties. - The available
unserialize_callback_func
only lets you load an apropriate class by name (which may not exist anymore).
- Reads the name of the original class from the
__PHP_Incomplete_Class
object. - It serializes the
__PHP_Incomplete_Class
object. - It modifies the resulting serialized string to convert the
__PHP_Incomplete_Class
object to astdClass
object. - It unserializes the modified string and reads all (now accessable) object properties into a key-value array.
- If a property value itself is a
__PHP_Incomplete_Class
object, it creates an instance ofIncompleteClassAccessor
for this value. (So it is recursive.)
<?php
namespace MyVendor\MyProject;
use hollodotme\IncompleteClassAccessor\IncompleteClassAccessor;
# 1. Read some serialized object
$serialized = file_get_contents( '/tmp/serialized.txt' );
# 2. Unserialize
$unserialzed = unserialize( $serialized );
# 3. Check for __PHP_Inclomplete_Class
if ( $unserialzed instanceof \__PHP_Inclomplete_Class )
{
$accessor = new IncompleteClassAccessor( $unserialized );
# Print the original class name
echo $accessor->getOriginalClassName();
# Print all properties
print_r( $accessor->getProperties() );
# Print a single property
echo $accessor->getProperty( 'someProperty' );
}
You are now able to map the old serialized object to an apropriate new one.
