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.
The windows version of PHP
has built in support for this extension. You do not
need to load any additional extension in order to use
these functions.
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 |
注: If you want to serialize non-ASCII characters you have to set the appropriate locale before doing so (see setlocale()).
