Question

I have a foreach like so:

foreach ($posts as $post) {

    $postArray[] = array(
    "title" => $post->title,
    "date" => date("d.m.Y", $post->created),
    // ... etc
  );

  var_dump($postArray);
}

$postArray is not delcared anywhere outside of this loop, and yet each loop iteration is ADDING to the existing array as if this variable is global, rather than creating a new one!

Is this a PHP setting? Bearing in mind I haven’t really changed any settings from whatever default WAMP gives me. Any ideas?

Answer 1

It is not a global variable but the way your syntax is written, it becomes global after the first iteration. This is because you are using the array_push shorthand of []. Usually we use this as a synonym to array_push()

What you want to do is this –

$postArray = array(
  ...
);

That way, on each iteration, you will get a brand new $postArray object.
