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.
A versão para Windows do PHP tem suporte embutido para esta extensão. Você não precisa carregar nenhuma extensão adicional para utilizar essas funções.
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.
This example will produce:
<wddxPacket version='1.0'><header comment='PHP packet'/><data> <string>PHP to WDDX packet example</string></data></wddxPacket> |
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> |
Nota: If you want to serialize non-ASCII characters you have to set the appropriate locale before doing so (see setlocale()).
