Unserialize in Java a serialized php object

Question

Does anyone know if it is possible, actually if it has been done, to serialize an object in php and unserialize it in Java (java-php communication). Maybe an adapter will be

Answer 1

Note that there's a Java implementation of PHP. So you may be able to serialise the object and pass it to your Java-PHP instance, deserialise and then call into your Java infrastructure.

It all sounds a bit of an unholy mess, but perhaps worth looking at!

Answer 2

There is serialized-php-parser, which is a Java implementation that can parse php-serialized objects. In general, if you have the choice, I wouldn't recommend php-serialized as an exchange format, because it isn't ascii-safe (It contains null-bytes). Go with a format like xml or json instead. If you need a bit of type-information, xmlrpc is a good choice. It has good implementations for both php and Java.

Answer 3

I remember a snippet for Drupal (PHP CMS) where this functionality was needed. Just found it, so take a look at Serialized drupal node objects to java (should work with any PHP serialized object).

Maybe you can use that. I don't know whether there are issues with newer versions of PHP.

Answer 4

add into pom.xml

<dependency>
    <groupId>de.ailis.pherialize</groupId>
    <artifactId>pherialize</artifactId>
    <version>1.2.1</version>
</dependency>

then in code use

MixedArray list = Pherialize.unserialize(data).toArray(); // data is string `enter code here`

Answer 5

You may be also interested in using PHP/Java bridge (http://php-java-bridge.sourceforge.net/). It has own protocol. In their site said that it's fast implementation of bridge.

Answer 6

Another Java project to work with the PHP serialization format is Pherialize.

Let's say you are serializing an array like this:

array(3) {
  [0]=>
  string(8) "A string"
  [1]=>
  int(12345)
  [2]=>
  bool(true)
}

Then you can unserialize it in Java with Pherialize like this:

MixedArray list = Pherialize.unserialize(data).toArray();
System.out.println("Item 1: " + list.getString(0));
System.out.println("Item 2: " + list.getInteger(1));
System.out.println("Item 3: " + list.getBoolean(2));
