PHP/JSON - stdClass Object

Question

I\'m pretty new to arrays still. I need some help - I have some JSON, and I\'ve run it through some PHP that basically parses the JSON and decodes it as follows:

Answer 1

You can use get_object_vars() to get an array of the object's properties, or call json_decode() with json_decode($string,true); to get an associative array.

Example:

<?php
$foo = array('123456' =>
 array('bar' =>
        array('foo'=>1,'bar'=>2)));


//as object
var_dump($opt1 = json_decode(json_encode($foo)));

echo $opt1->{'123456'}->bar->foo;

foreach(get_object_vars($opt1->{'123456'}->bar) as $key => $value){
    echo $key.':'.$value.PHP_EOL;
}

//as array
var_dump($opt2 = json_decode(json_encode($foo),true));

echo $opt2['123456']['bar']['foo'];

foreach($opt2['123456']['bar'] as $key => $value){
    echo $key.':'.$value.PHP_EOL;
}
?>

Output:

object(stdClass)#1 (1) {
  ["123456"]=>
  object(stdClass)#2 (1) {
    ["bar"]=>
    object(stdClass)#3 (2) {
      ["foo"]=>
      int(1)
      ["bar"]=>
      int(2)
    }
  }
}
1
foo:1
bar:2

array(1) {
  [123456]=>
  array(1) {
    ["bar"]=>
    array(2) {
      ["foo"]=>
      int(1)
      ["bar"]=>
      int(2)
    }
  }
}
1
foo:1
bar:2

Answer 2

You can iterate on the stdClass with foreach.
