I am trying to recurse through a multidimensional Object/Array structure to create JSON, but the following isn't working. $data is reset, but I'm not sure how to prevent this.
public function encodeJSON($data) {
foreach ($data as $key => $value) {
if (is_array($value) || is_object($value)) {
$json->$key = $this->encodeJSON($value);
} else {
$json->$key = $value;
}
}
return json_encode($json);
}
If you're trying to learn recursion that's one thing, but at least for me json_encode automatically encodes objects and arrays recursively so it's not really necessary to write the extra function.
Tested with this code:
class TestClass {
var $c1;
var $c2;
function __construct() {
$this->c1 = 'member variable 1';
$this->c2 = 8080;
}
}
$test = array('hello' => 'world', 'age' => 30,
'arr' => array('a' => 'b', 'c' => 'd'), 'obj' => new TestClass());
echo(json_encode($test));
// I get the following JSON object:
// {"hello":"world","age":30,"arr":{"a":"b","c":"d"},"obj":{"c1":"member variable 1","c2":8080}}
$datais not reset. It produces one string with all of the values including nested arrays. I tested it on several arrays.{"foo":"{\"bar\":\"baz\"}"}instead of the intended{"foo":{"bar":"baz"}}. You need to encode the whole object/array at once.json_encode($data);? json_encode() is perfectly capable of serializing arrays and objects!
