    wddx 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 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()).
