    A function to use for dates with PHP & WDDX
    getdate()

    $ta="<FORM><TEXTAREA rows=15 cols=80>" ;
    $te="</TEXTAREA></FORM>";
    $packet_id=wddx_packet_start("Date Example--");
    $myDate=getdate();
    wddx_add_vars($packet_id,'myDate');
    $package=wddx_packet_end($packet_id);
    print($ta.$package.$te);

    Produces:

    <wddxPacket version='1.0'><header><comment>Date Example--</comment></header>
    <data><struct><var name='myDate'>
    <struct><var name='seconds'><number>12</number></var>
    <var name='minutes'><number>55</number></var>
    <var name='hours'><number>1</number></var>
    <var name='mday'><number>13</number></var>
    <var name='wday'><number>1</number></var>
    <var name='mon'><number>10</number></var>
    <var name='year'><number>2003</number></var>
    <var name='yday'><number>285</number></var>
    <var name='weekday'><string>Monday</string></var>
    <var name='month'><string>October</string></var>
    <var name='0'><number>1066031712</number>
    </var></struct></var></struct></data></wddxPacket>

    The above feature will cause a slight trouble since the name of the variable will always be "wddxtemp" but you can use preg_replace to fix that.

    Also, a better approach is to serialize the entire class. WDDX will that write a reserved "php_class_name" variable which can be used to reconstruct the class during a deserialize.

    You can use globals to get around the above in classes:

    <?php
    class Test
    {
      var     $str;
      var     $wddx;

      function     Test()
      {
            $this->str = "test";
            $this->wddx_serialize($this->str);
            header('Content-Type: text/xml');
        echo (    $this->wddx);
      }
     
      function     wddx_serialize($var) {
        global     $wddxtemp;
        unset(    $wddxtemp);
            $wddxtemp = $var;
            $this->wddx = wddx_serialize_vars("wddxtemp");
      }
    }

    new     Test();
    ?>

    Be careful using WDDX - functions on object variables. As I just had to find out the following won't work:

    <?php
    class Test
    {
      var     $str;
      var     $wddx;

      function     Test()
      {
            $this->str = "test";
            $this->wddx = wddx_serialize_vars("this->str");
        print(    htmlentities($this->wddx));
      }
    }

    new     Test();
    ?>

    That's what you'll get:
    <wddxPacket version='1.0'><header/><data><struct></struct></data></wddxPacket>
