/**
 * Deserializes a serialized PHP data structure into corresponding Java objects. It supports
 * the integer, float, boolean, string primitives that are mapped to their Java
 * equivalent, plus arrays that are parsed into <code>Map</code> instances and objects
 * that are represented by {@link PhpObject} instances.
 * <p>
 * Example of use:
 * <pre>
 * 		String input = "O:8:"TypeName":1:{s:3:"foo";s:3:"bar";}";
 * 		SerializedPhpParser serializedPhpParser = new SerializedPhpParser(input);
 *		Object result = serializedPhpParser.parse();
 * </pre>
 *
 * The <code>result</code> object will be a <code>PhpObject</code> with the name "TypeName" and
 * the attribute "foo" = "bar".
