Re: Simple array checking?

Sorry about the unmatched bracket, mistyped into perlmonks!! line 163=

if(!(@{$createdFiles->{$streamID}}||@{$modifiedFiles->{$streamID}}||@{
+$deletedFiles->{$streamID}})) 
{ 
    exit; 
};

Can't use an undefined value as an ARRAY reference at E:\Inetpub\cgi-b
+in\wms.pl line 163.

I have already declared $createdFiles a a hash, the undefined value is i assume the key. I just want to know if they exit or not, i will try the exists function.

Alright, now we are getting somewhere. :) Here's what you can do: `# !@{$array_ref} <-- Perl will complain about this if $array_ref is un +defined # $#{$array_ref} <-- but not this if($#{$createdFiles->{$streamID}} == -1){ print "Empty\n"; }` [download] --perlpelxer	[reply] [d/l]
