This article mainly introduces the PHPJSON error: CannotuseobjectoftypestdClassasarray solution. if you need to call json_decode to generate a json object from a string object by referring to php, if you use the [] operator to retrieve data, the following error is returned:

The code is as follows:

Cannot use object of type stdClass as array

Cause:

The code is as follows:

$ Res = json_decode ($ res );
$ Res ['key']; // use the object after json_decode () as an array.

Solution (2 types ):

1. use json_decode ($ d, true ). The second variable of json_decode is set to true.
2. json_decode ($ res) returns an object. you cannot use $ res ['key'] for access. you can replace it with $ res-> key.
