Thank you Michel
You;ve understand correct the question. Thank you for the removing new
keyword
Everything you've said is exact but using following snippet
$b = array('one' => 'bla', 'two' => 'blabla', 'three' => 'blablabla');
while(list($k, $v) = each($b)) {
print "$k - $v";
}
the result will be
0 - bla
one - bla
0 (the key) = 'bla' (the value)
one (the key of the *same* element) = 'bla' (the *same* value)
and so on ...
