Json array of objects in php

Question

this is the json that my code produces

{
"aaa":1,
"b":2,
"c":3,
"d":4,
"e":5,
"fff":{"a":11111,"b":222222,"c":33333,"d":444454,"e":55555555}
}

and this is the code

<?php
$c = array('a' => 11111, 'b' => 222222, 'c' => 33333, 'd' => 444454, 'e' => 55555555 );
$arr = array('aaa' => 1, 'b' => 2, 'c' => 3, 'd' => 4, 'e' => 5 , 'fff'=>$c);
echo json_encode($arr);
?>

but I want to have some structure like this

{
"aaa":1,
"b":2,
"c":3,
"d":4,
"e":5,
"fff":{"a":11111,"b":222222,"c":33333,"d":444454,"e":55555555},
"last":[
 {
 "id": 8817,
 "loc": "NEW YORK CITY"
 },
 {
 "id": 2873,
 "loc": "UNITED STATES"
 },
 {
 "id": 1501,
 "loc": "NEW YORK STATE"
 }
 ]
}

I am new in json and php and I need this fast so I do not have time to read about this json structure... So please if someone know how to add this last element please provide some php code.

Thanks,

• deceze: Uhm... just add a "last" array to your $arr?

Answer 1

• Take the "json-encoded" string and pass it to json_decode()
• assign the return value to a variable
• pass that variable to var_export() to get a "php-encoded" string representation of the data.

e.g.

<?php
$json = '{
"aaa":1,
"b":2,
"c":3,
"d":4,
"e":5,
"fff":{"a":11111,"b":222222,"c":33333,"d":444454,"e":55555555},
"last":[
 {
 "id": 8817,
 "loc": "NEW YORK CITY"
 },
 {
 "id": 2873,
 "loc": "UNITED STATES"
 },
 {
 "id": 1501,
 "loc": "NEW YORK STATE"
 }
 ]
}';
$php = json_decode($json, true);
echo var_export($php);

prints

array (
 'aaa' => 1,
 'b' => 2,
 'c' => 3,
 'd' => 4,
 'e' => 5,
 'fff' => 
 array (
 'a' => 11111,
 'b' => 222222,
 'c' => 33333,
 'd' => 444454,
 'e' => 55555555,
 ),
 'last' => 
 array (
 0 => 
 array (
 'id' => 8817,
 'loc' => 'NEW YORK CITY',
 ),
 1 => 
 array (
 'id' => 2873,
 'loc' => 'UNITED STATES',
 ),
 2 => 
 array (
 'id' => 1501,
 'loc' => 'NEW YORK STATE',
 ),
 ),
)

• Damien: Damned, I was writing the resulting php code manualy! Clever use of var_export :-) Just to make the answer clearer, an array with not numeric keys is translated to an object (with {}) and a numeric keys array to an array (with []).
• nickb: I do not understand how this answers the OP?
• deceze: @Damien An array with continuous numeric keys. array(1 => 'foo', 0 => 'bar') will be encoded as an object as well (at least in some versions of PHP, AFAIR).
• VolkerK: nickb, I assumed (wild-guessing-mode) the op had a some javascript object literal as a template and wanted a congruent php template. And via json_decode/var_export one can create such a php template. Not rocket science, but ...
