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.
La versione per Windows di PHP ha già compilato il supporto per questo modulo. Non occorre caricare alcun modulo addizionale per potere utilizzare queste funzioni.
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()).
