PHP second-level array conversion json

: This article describes how to convert PHP second-level array to json. if you are interested in the PHP Tutorial, refer to it. PHP provides functions to directly convert array to json

Json_encode ($ param_array );

What if we need the following nested formula?

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

A second-level array is constructed first, and then json_encode conversion is called.

$ Param = array ('userid' => 'bonni'); $ params = array ('appid '=> '20140901', 'nonce' => $ nonce, 'timestamp' => $ timestamp, 'signature' => $ signature, 'paramam' => $ 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) ;}) ;}; script

The above describes the second-level array conversion of json in PHP, including the content, and hope to be helpful to friends who are interested in PHP tutorials.
