XLIV. WDDX functions

Table of Contents
wddx_serialize_value
wddx_serialize_vars
wddx_packet_start
wddx_packet_end
wddx_add_vars
wddx_deserialize

These functions are intended for work with WDDX.

Note that 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

<?php
print wddx_serialize_value("PHP to WDDX packet example", "PHP packet");
?>
     

This example will produce:

<wddxPacket version='0.9'><header comment='PHP packet'/><data>
<string>PHP to WDDX packet example</string></data></wddxPacket>
     

Example 2. Using incremental packets

<?php
$pi = 3.1415926;
$packet_id = wddx_packet_start("PHP");
wddx_add_vars($packet_id, "pi");

/* Suppose $cities came from database */
$cities = array("Austin", "Novato", "Seattle");
wddx_add_vars($packet_id, "cities");

$packet = wddx_packet_end($packet_id);
print $packet;
?>
     

This example will produce:

<wddxPacket version='0.9'><header comment='PHP'/><data><struct>
<var name='pi'><number>3.1415926</number></var><var name='cities'>
<array length='3'><string>Austin</string><string>Novato</string>
<string>Seattle</string></array></var></struct></data></wddxPacket>
