I'm pulling in a search from the Twitter api, fetching the data with file_get_contents and then passing to json_decode which give me this array structure.

     "text":"Ich R U #BoysNoize #SuperRola",




This repeats for every tweet pulled, Now I can access the user name and text using a foreach loop and assigning every instance of results to a variable, then pulling data from the variable.

foreach($jsonArr['results'] as $item){    

// Takes the Array jsonArr and for every results heading creates an $item

    $user = mysql_real_escape_string($item['from_user']);
    $text = mysql_real_escape_string($item['text']);

This saves the correct variables OK, But I can't seem to get the the data within the entities array within the results. If I print out the Entities var like the username or text I get


So It holds the arrays for each results returned but how on earth do I access it, I've been messing around with a few other methods I know for accessing array data but they all seem to fall flat. Any help with how to get at these values, or integrate them with the foreach would be greatly appreciated



Assuming that you've chosen to decode the JSON as a multi-dimensional array, rather than as objects:

foreach ($results as $tweet) {
    $user = $tweet["from-user"];
    $text = $tweet["text"];

    $entities = $tweet["enities"];
    $urls = $entities["urls"];

    foreach ($urls as $url) {
        echo $url["expanded_url"];

et cetera

You could use json_decode to decode the already encoded field and then add the result in the $res array.

If the array keys in your PHP array are not consecutive numbers, json_encode() must make the other construct an object since JavaScript arrays are always consecutively numerically indexed.

Use array_values() on the outer structure in PHP to discard the original array keys and replace them with zero-based consecutive numbering:


// Non-consecutive 3number keys are OK for PHP
// but not for a JavaScript array
$array = array(
  2 => array("Afghanistan", 32, 13),
  4 => array("Albania", 32, 12)

// array_values() removes the original keys and replaces
// with plain consecutive numbers
$out = array_values($array);
// [["Afghanistan", 32, 13], ["Albania", 32, 12]]

It is pretty obvious that array[10] is faster than array.get(10), as the later internally does the same call, but adds the overhead for the function call plus additional checks.

Modern JITs however will optimize this to a degree, that you rarely have to worry about this, unless you have a very performance critical application and this has been measured to be your bottleneck.

To get all from phoneNumbers:

DECLARE @json nvarchar(max)=
      "firstName": "John",
      "lastName" : "doe",
      "age"      : 26,
      "address"  : {
        "streetAddress": "naist street",
        "city"         : "Nara",
        "postalCode"   : "630-0192"
      "phoneNumbers": [
          "type"  : "iPhone",
          "number": "0123-4567-8888"
          "type"  : "home",
          "number": "0123-4567-8910"

    SELECT [Type], [Number]
    FROM OPENJSON( @json, '$.phoneNumbers' ) 
    WITH ([Type] NVARCHAR(25) '$.type', [Number] NVARCHAR(25) '$.number');
