Hi all!

Has it been always the way, that it is not possible to use current() in a
foreach loop?

Just stumbled upon (using php 5.5.5):

$arr = array( "a", "b", "c" );

foreach( $arr as $entry )
{
    #var_dump( current($arr) );
}

var_dump( current($arr) );

Which yields "false", because the internal array pointer points behind the
last element of $arr.
If I uncomment the inner var_dump(), the script outputs "b" four times.
This seems odd... I know that the documentation advises not to fiddle with
the internal array pointer in a foreach loop, but current() should not
affect it in any way and therefor should be safe to use.

Does anyone know what the reasoning behind this behavious is?

Greetings

Nico
