Accessing nested values in PHP json_encode

Question

I converted an array to JSON, how do I get the value of the slug from it?

{
  "230": {
    "term_id": 230,
    "name": "Executive Committee",
    "slug": "executive_committee",
    "term_group": 0,
    "term_taxonomy_id": 241,
    "taxonomy": "team_member_filter",
    "description": "",
    "parent": 0,
    "count": 1,
    "object_id": 1561,
    "filter": "raw"
  }
}

Of course the first value "230" is different for each instance. How do I access the "slug" value for each instance inside of my loop?

I originally had this array in $variable:

  Array ( 
   [230] => stdClass Object ( 
      [term_id] => 230
      [name] => Executive Committee 
      [slug] => executive_committee
      [term_group] => 0 
      [term_taxonomy_id] => 241 
      [taxonomy] => team_member_filter
      [description] =>
      [parent] => 0 
      [count] => 1 
      [object_id] => 1561 
      [filter] => raw 
   )   
)

Why does $variable['slug'] not return anything?

Can you show the actual code that you have?

Use json_decode() and then you can access like an array:

$items = json_decode($variable, true); // 'true' here makes the json an associative array
foreach($items AS $item) {
    echo $item['slug']; // because it is associative  you can access each value by name
}

This echos executive_committee for the JSON you provided above.

From the original array ($variable)you would do the same thing:

foreach($variable AS $item) {
    echo $item->slug; // because you have an object, not an array 
}

I was actually using json_encode from the original array because $item['slug'] was not returning anything. How do I make the original array associative?

Jay Blanchard Over a year ago

You original array was associative to begin with. If you'd like to edit your post above, adding your original array, I'll edit my answer.

Cool - guess what? The same foreach() code will work! ¯\_(ツ)_/¯

ha, $item['slug'] is not returning anything for me. It is inside of the default wordpress loop. If I just print_r $items, the array for each post gets printed. But as soon as I add ['slug'], I get nothing

It is because slug is nested within the array item. You have to loop through $variable.
