Entry

Is the order of entries in an associative array guaranteed?

What order are entries in an associative array returned by each()?

Say you have something like this:

    $myarray['a'] = 'a';
    $myarray['b'] = 'b';
    $myarray['c'] = 'c';

and do this:

    reset($myarray);
    while(list($key, $val) = each($myarray)) echo "Key: $key<br>";

It will print

    Key: a
    Key: b
    Key: c

This first in first out order is guaranteed.
