When you want to loop into a multiple dimensions array  you can use foreach like this   foreach  data as  users      foreach  users as  user         echo  user  id        user  c name        user  seat no     lt br  gt

As you re passing true as the second parameter to json decode  in the above example you can retrieve data doing something similar to    myArray   json decode  data  true   echo  myArray 0   id       Fetches the first ID echo  myArray 0   c name       Fetches the first c name        echo  myArray 2   id       Fetches the third ID    etc     If you do NOT pass true as the second parameter to json decode it would instead return it as an object   echo  myArray 0 - gt id
