Question

I was wondering if foreach() works when the array looks like this:

• arr_name[eggs] = something
• arr_name[pencil] = something else

Will foreach work if run as:

foreach(arr_name as $key => $value)

for they keys that have a non-numerical value ?

Answer 1

Yes, foreach supports any kind of key. In your case, $key will be a string, 'eggs' and 'pencil' respectively for each item. In fact, foreach was intended for use with arrays that have non-numerical keys which you can’t easily iterate using for.
