This article will explain in detail how php converts json to array type. The editor thinks it is very practical, so I share it with you for reference. I hope you can get something after reading this article.
In php, you can use the json_decode () function to convert json data to an array type, and you only need to specify that the second parameter of the function is a Boolean value "true" to decode the JSON value into an associative array; the syntax format is "json_decode ($json, true)".

Let's take a look at the basic syntax of the json_decode () function:
Json_decode ($json, $assoc = FALSE, $depth = 512, $options = 0)
The json_decode () function accepts the four parameters described above, as follows:
Json: it contains the JSON string that needs to be decoded. It applies only to UTF-8-encoded strings.
Assoc: it is a Boolean variable. If true, the returned object is converted to an associative array.
Depth: it represents the recursive depth specified by the user.
Options: it includes the bitmask of JSON_OBJECT_AS_ARRAY, JSON_BIGINT_AS_STRING,JSON_THROW_ON_ERROR.
Return value: this function returns the encoded JSON value with the appropriate PHP type. Returns NULL if json cannot decode or if the encoded data is deeper than the recursive limit.
