What is PhpDig?
PhpDig is a PHP MySQL based
Web Spider & Search Engine.



wddx_add_vars — Adds one or more variables to a WDDX packet.


bool wddx_add_vars(packetID, var1[, var2]);
int packetID: Packet ID
mixed var1: Name of variable to add
mixed var2 (optional): Name of variable to add


TRUE on success; FALSE on error


This function adds one or more variables to the packet identified with argument one, the packet ID. Note that you pass the variable name (such as "foo"), not the variable itself (such as $foo).

You can supply multiple variables to be added in one step. Regardless of the number of variables, PHP creates a WDDX STRUCT packet. This functions the same way as wddx_serialize_vars() .


Existing since versions 3.0.7 and 4.0


Example 1413. Create a WDDX packet

<wddxPacket version='1.0'>
<var name='foo'><string>FOO</string></var>
<var name='bar'><string>BAR</string></var>

$foo = "FOO";
$bar = "BAR";

// create a new packet
$id = wddx_packet_start();
wddx_add_vars($id, "foo", "bar");
$packet = wddx_packet_end($id);

// show output
echo $packet;
