PHP : Function Reference : WDDX Functions : wddx_serialize_vars

wddx_serialize_vars

Serialize variables into a WDDX packet (PHP 4, PHP 5)
string wddx_serialize_vars ( mixed var_name [, mixed ...] )

Example 2614. wddx_serialize_vars() example

copy to clipboard
<?php
$a = 1;
$b = 5.5;
$c = array("blue", "orange", "violet");
$d = "colors";

$clvars = array("c", "d");
echo wddx_serialize_vars("a", "b", $clvars);
?>

The above example will output:

copy to clipboard
<wddxPacket version='1.0'><header/><data><struct><var name='a'><number>1</number></var>
<var name='b'><number>5.5</number></var><var name='c'><array length='3'>
<string>blue</string><string>orange</string><string>violet</string></array></var>
<var name='d'><string>colors</string></var></struct></data></wddxPacket>

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>

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>
