Introductie
These functions are intended for work with WDDX.
Afhankelijkheden
In order to use WDDX, you will need to install the expat library
(which comes with Apache 1.3.7 or higher).
Installatie
After installing expat compile PHP with
--enable-wddx.
Deze functies worden automatisch ingebouwd in de
windows versie van PHP. Er zijn geen extra handelingen nodig om deze
functies te gebruiken.
Configuratie tijdens scriptuitvoer
Deze extensie gebruikt geen configuratie regels.
Resource types
Deze extensie maakt geen gebruik van resources.
Voorgedefineerde constanten
Deze extensie definieert geen constanten.
Voorbeelden
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.
Voorbeeld 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> |
|
Voorbeeld 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> |

Opmerking:
If you want to serialize non-ASCII characters you have to set
the appropriate locale before doing so (see
setlocale()).
