Примеры
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.
Пример #1 Serializing a single value with WDDX
<?php
echo wddx_serialize_value("PHP to WDDX packet example", "PHP packet");
?>
This example will produce:
<wddxPacket version='1.0'><header comment='PHP packet'/><data> <string>PHP to WDDX packet example</string></data></wddxPacket>
Пример #2 Using incremental packets with WDDX
<?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);
echo $packet;
?>
This example will produce:
<wddxPacket version='1.0'><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>
Замечание: If you want to serialize non-ASCII characters you have to convert your data to UTF-8 first (see utf8_encode() and iconv()).
