These functions are intended for work with WDDX.
In order to use WDDX, you will need to install the expat library
(which comes with Apache 1.3.7 or higher).
After installing expat compile PHP with
--enable-wddx.
Η έκδοση για windows της PHP έχει ενσωματωμένη υποστήριξη για αυτή την επέκταση. Δεν χρειάζεται να φορτώσετε κάποια πρόσθετη επέκταση για να χρησιμοποιήσετε αυτές τις συναρτήσεις.
Αυτή η επέκταση δεν έχει directives ρύθμισης ορισμένα στο php.ini.
Αυτή η επέκταση δεν έχει resource τύπους ορισμένους.
Αυτή η επέκταση δεν έχει σταθερές ορισμένες.
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.
ÐáñÜäåéãìá 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> |
|
ÐáñÜäåéãìá 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> |

Óçìåßùóç:
If you want to serialize non-ASCII characters you have to convert
your data to UTF-8 first (see utf8_encode() and
iconv()).
