Re: looping through array references

I use the following because it limits the scope of the two variables, $item and $hash_ref, to the loop where they are used.

for my $item ( 0 .. $#{$ref} ) {
    $hash_ref = $ref->[$item];
    print "$hash_ref->{'key1'};
}

It also continues to work when you add extra code that includes a next or redo statement.

Update fixed code thanks to johngg. Teach me to post without running it first;)

I think there are a couple of problems with your code: `for my $item ( 0 .. @{$ref} )` is going to try to access an element beyond the end of the array. What you need here is `$#{$ref}`. `$hash_ref = $ref->{$item};` should be `$hash_ref = $ref->[$item];` as you are dereferencing an array, not a hash Cheers, JohnGG	[reply] [d/l] [select]
