Class PHP2Map

java.lang.Object

org.qbroker.common.PHP2Map

public class PHP2Map
extends java.lang.Object

PHP2Map parses a PHP serialized text stream and maps the structural content of the PHP object into Java object stored in a Map. It only recognizes two basic Java objects, String, Map. A Map can contain any objects of the two types. They are the nodes of the data tree. A String is only a leaf in the data tree. For PHP's numbers, decimals and boolean values, they will be stored as String. For PHP's null, it will stored as null. The PHP Object is treated same as a Map with single key pointing to a PHP Array. A PHP Array is treated as a Map. With these two basic types of objects, any data structures will be representable. The mapping is one-to-one in one way at least. It exposes the structure data.

The method of parse() returned a Map. The PHP data are stored in the key of "PHP".
