I don't know how to read it til "TenCty": "CMC Data Center"
, and how can I replace "CMC Data Center" with something else and save it in maps.json
file.
When users submit a form, information will save in MySqli and also save in json file? Is it possible? In javascript or PHP will ok.
This json file is map's information to show in Leaflet, so I must save as json. Any sugguestions? And thanks in advance
Object
, then use the simple object manipulation methods to make whatever changes you need, then you canJSON.stringify
the object back to JSON if you want ... similarly in PHP, I think the parse/stringify areJSON_decode
/JSON_encode
