CVI. WDDX Functions

Introduction

These functions are intended for work with WDDX.

Requirements

In order to use WDDX, you will need to install the expat library (which comes with Apache 1.3.7 or higher).

Installation

After installing expat compile PHP with --enable-wddx.

The windows version of PHP has built in support for this extension. You do not need to load any additional extension in order to use these functions.

Runtime Configuration

This extension has no configuration directives defined in php.ini.

Resource Types

This extension has no resource types defined.

Predefined Constants

This extension has no constants defined.

Examples

All the functions that serialize variables use the first element of an array to determine whether the array is to be serialized into an array or structure. If the first element has string key, then it is serialized into a structure, otherwise, into an array.

Example 1. Serializing a single value

This example will produce:

PHP to WDDX packet example

Example 2. Using incremental packets

This example will produce:

Note: If you want to serialize non-ASCII characters you have to set the appropriate locale before doing so (see setlocale()).
