Converting arrays into JSON in PHP Powerful PHP already provides built-in functions: Json_encode () and Json_decode (). It's easy to understand that Json_encode () is converting a PHP array into JSON. Instead, Json_decode () converts JSON into a PHP array. For example:

I,Brief Introduction to JSONIn terms of structure, all data can be divided into three types: The first type is scalar (scalar), which is a separate string or number (numbers), such as the word "Beijing.The second type is sequence (sequence), that is, several related data are listed in a certain order, also called array or list, for example, "Beijing, tokyo ".The third type is mapping, that is, a name/value pair (name/value), that is, the data has a na

The problem with this article is that PHP's non-indexed arrays are converted to JSON objects (rather than the default JSON array)The method used by the array to JSON in PHP is the system's own: Json_encodeThe rules for array-to-
