I keep getting a warning when I put an array in a foreach loop

Question

Here is my code.

function displayTweets($object){
    $myArray = json_decode(json_encode($object), true);
    foreach ($myArray["statuses"] as $tweet){

It gives me a warning when I use line 3 of my code. The $object passed in the parameter is a json object and I am trying to for loop through it and display tweets. The code at first doesn't produce warnings but then out of no where it will and it pops my page with a warning box. How can I stop this warning message? Is it okay to use $myArray["statuses"] ?

KeyMaker13 check $myArray contains status index or not. You can use isset(), !empty(), array_key_exists() — Death-is-the-real-truth

You can try this

function displayTweets($object){
   $myArray = json_decode(json_encode($object), true);
   if(array_key_exists("statuses", $myArray) {
      foreach ($myArray["statuses"] as $tweet){
      // Your code
      }
    }
 }

Check to see if $myArray actually contains the statuses key before using it.

if(isset($myArray['statuses'])) {
  // $myArray contains statuses, execute the for loop
}
