Question

I can’t find an answer to this anywhere.

foreach ($multiarr as $array) {
   foreach ($array as $key=>$val) {
      $newarray[$key] = $val;
   }
}

say $key has duplicate names, so when I am trying to push into $newarray it actually looks like this:

$newarray['Fruit'] = 'Apples';
$newarray['Fruit'] = 'Bananas';
$newarray['Fruit'] = 'Oranges';

The problem is, the above example just replaces the old value, instead of pushing into it.

Is it possible to push values like this?

Answer 1

Yes, notice the new pair of square brackets:

foreach ($multiarr as $array) {
   foreach ($array as $key=>$val) {
      $newarray[$key][] = $val;
   }
}

You may also use array_push(), introducing a bit of overhead, but I’d stick with the shorthand most of the time.
