How to deserialize in PHP an object serialized in Java

Question

Is there any way to deserialize in PHP an object serialized in Java? IE If I have a Java class that implements Serialization and I use an ObjectOutputStream to write the object, and convert the result to a string, is there a way in PHP to take that string and create a similar object representation from it?

What does the Java Serialized data look like?

I would heavily recommend you don't do this. Java serialization is meant for a Java instance to both save and load the data (for either transmission to another Java application or persistence between invocations of the same application). It was not at all meant to be a cross-platform protocol.

I would advise you to make an API adapter layer between the two. Output the contents of your Java object to a format you can work with in PHP, be it XML, YAML, or even a binary format (where you could use DataOutputStream).
