PHP multidimensional array to JSON

Question

So im trying to figure out the best way to get MySql table data into either a multidimensional PHP array or convert that multidimensional array into a json string.

Answer 1

That is not valid JSON. The structure you are looking for would be something like:

[
 {"key1": ["package1", "package2", "package3"]},
 {"key2": ["package1", "package2", "package3", "package4"}]
          ^ An array as the value to the key "key1", "key2", etc..
]

At the PHP side, you would need something like:

1. For every row fetched from MySQL
   • $arr[$key] =
   • for each package:
     • append package to $arr[$key]
2. echo out json_encode($arr)
