about foreach

[Amir]

Hi,
I want to use a foreach in PERL in a way that on of the strings inside
it is empty string.
this is my foreach:
foreach my $var ( qw ( Hi Fofo) ) {
..
..
..
}
I want to add to the foreach that the $var will be an empty string and
Hi and Fofo.
do you know how can I do it
thanks in advance

Hi,
I want to use a foreach in PERL

That should be "Perl" (the language) or "perl" (the program), not "PERL".

in a way that on of the strings inside
it is empty string.
this is my foreach:
foreach my $var ( qw ( Hi Fofo) ) {
.
.
.
}
I want to add to the foreach that the $var will be an empty string and
Hi and Fofo.
do you know how can I do it

Your problem is that you can't specify an empty string using qw().

so try:

foreach my $var ( '', 'Hi', 'Fofo' ) { ...

or

foreach my $var ( '', qw(Hi Fofo) ) { ...
