Php uses json_decode to forcibly convert json data to an array

A simple example of php using json_decode to forcibly convert json data into arrays. We use var_dump (json_decode ($ str, true )); convert json to the data we want.

The Code is as follows:	Copy code
$ A ['D'] [] = 1; $ A ['D'] [] = 2; Echo $ str = json_encode (array ($ )); Var_dump (json_decode ($ str ));

Conversion code

The Code is as follows:	Copy code
Array (1 ){ [0] => Object (stdClass) #1 (1 ){ ["D"] => Array (2 ){ [0] => Int (1) [1] => Int (2) } } }

As you can see, this is an object in an array;
We force the json_decode result to be converted to an array. -- add the parameter to the fourth row.

The Code is as follows:	Copy code
Var_dump (json_decode ($ str, true )); Array (1 ){ [0] => Array (1 ){ ["D"] => Array (2 ){ [0] => Int (1) [1] => Int (2) } } }
