<p>I noticed the problem when trying ot use :<br>
xavp_params_implode followed by xavp_params_explode no luck with that because<br>
xavp_params_explode will fail to parse emtpy params.</p>
<p>Example:<br>
<code>$xavp(x[0]=>y) = "";</code></p>
<p>Will fail to parse because <code>y=;</code> is consider invalid by the param parser.</p>
<p>Glad to see that the core was exposing a reusable serialize function !</p>
