# wddx_serialize_vars

wddx_serialize_vars -- Serialize variables into a WDDX packet

## Description

`string wddx_serialize_vars`(mixed var_name, mixed [...] );

wddx_serialize_vars() is used to create a WDDX packet with a structure that contains the serialized representation of the passed variables.

wddx_serialize_vars() takes a variable number of arguments, each of which can be either a string naming a variable or an array containing strings naming the variables or another array, etc.

Example 1. wddx_serialize_vars example

      1
      2 <?php
      3 $a = 1;
      4 $b = 5.5;
      5 $c = array("blue", "orange", "violet");
      6 $d = "colors";
      7
      8 $clvars = array("c", "d");
      9 print wddx_serialize_vars("a", "b", $clvars);
     10 ?>
     11

The above example will produce:

      1
      2 <wddxPacket version='0.9'><header/><data><struct><var name='a'><number>1</number></var>
      3 <var name='b'><number>5.5</number></var><var name='c'><array length='3'>
      4 <string>blue</string><string>orange</string><string>violet</string></array></var>
      5 <var name='d'><string>colors</string></var></struct></data></wddxPacket>
