PHP序列化所有POST数据

I want to serialize all POST data from HTML form with PHP. I have tried with this code: serialize($_POST); but as result I get serialized INPUT Names and Values together, I want to get serialized only Values of INPUT.

if you need to serialize only array values - use array_values function. After using this function you will have your array values, but keys will be numeric:

serialize(array_values($_POST))
