Re^2: Help with PHP-to-Perl CPAN bundle

foreach my $alias (@array) creates an alias to the @array entry. Mutiple aliases in the loop aren't possible. (In PHP you can do for ($hash => $key, $value) {...} to do multiple aliases)

Unless I'm misunderstanding this (not knowing PHP), then what you are looking for here is each. eg:

   while (my ($key, $value) = each %hash ) { .. }

Or am I way off the mark?

`$key, $value` are copies of the values in the hash. The => operator can be used in PHP to create aliases to the elements, so changing `$value` is the same as changing `$hash{$key}` (to use Perlish syntax). So, in PHP: `$array = (0,1,2,3,4,5); for ($array => $a, $b, $c) { $c = 'two'; } print ($array[2]) #Prints 'two'` [download] Cheers, Erik Light a man a fire, he's warm for a day.

$key, $value

$value

$hash{$key}

$array = (0,1,2,3,4,5);
for ($array => $a, $b, $c) {
  $c = 'two';
}

print ($array[2]) #Prints 'two'
