PHP level two array conversion json

PHP provides functions to directly convert an array into JSON

json_encode($param_array);

What if the following nested type is required to handle this?

{    "appid""1500001105",    "nonce"32490,    "timestamp"1458195253,    "signature""bf13fe77f46a96edba1a0e2b84fce66580b2f50b",    "param": {        "userid""bonnie"    }}

First form a level two array, then call Json_encode conversion.

$paramarray(    'userid'=>'bonnie');$paramsarray(    'appid'=>'1500001105',    'nonce'=>$nonce,    'timestamp'=>$timestamp,    'signature'=>$signature,    'param'=>$param,);$params_json = json_encode($params);

'). addclass (' pre-numbering '). Hide (); $ (this). addclass (' has-numbering '). Parent (). append ($numbering); for (i = 1; i <= lines; i++) {$numbering. Append ($ ('

'). Text (i)); }; $numbering. FadeIn (1700); }); });

The above describes the PHP two-level array conversion json, including the aspects of the content, I hope the PHP tutorial interested in a friend helpful.
