echo "$gooshgoosh[$i]['num']";

Does anyone here know why it echos

array['num']

PHP will only evaluate interpolated expression to the first array index, or the first attempt to dereference an object. This means that these won't work as expected:

echo "$array[id1][id2]";    // like "{$array[id1]}[id2]"
echo "$object->obj1->obj2"; // like "{$object->obj1}->obj2"

You can force PHP to evaluate the entire expression using curly braces:

echo "{$array[id1][id2]}";
echo "{$object->obj1->obj2}";

In your particular case, PHP was evaluating "$gooshgoosh[$i]", which resolved to an array. Array to string conversion yields the string "array", so that string was substituted in yielding "array['num']".

This happens because of quotes: PHP does not understand, that ['num'] is array index. Try this:

echo $gooshgoosh[$i]['num'];
