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 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>
Example #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>
Note:
If you want to serialize non-ASCII characters you
have to convert your data to UTF-8 first (see utf8_encode() and iconv()).
