Converting a array to a scalar

Is there any good function to convert an array (this is the content of a fil
e) to scalar (for email sending as the body)

Is there any good function to convert an array (this is the content of a
file) to scalar (for email sending as the body)



I am not sure I understand your questions but I have recently had success
with the module Text-Template... You may wish to look at that module.

If you can send us some code that may help...

jwm

I found a quite easy way to do that.

$content="@the_array";

Is the above method good or am i missing something?

Perhaps the module you are using can do this for you.  If not,
it *may* convert newline sequences to the correct type.  Not
enough information.

Anyway, the normal way to perform this task is to use join.

my $scalar = join "\n", @array;

The above example will join each line together, with a newline
between each.  There won't be a newline on the last line, unless
you add it on.

If you need more information, please include the module name
you are using.

That is the same as:

$content = join $", @the_array;

So if you want to have the array separated by the contents of the $" variabl
e
which defaults to ' '?

Thanks that also worked $content=join "", @the_array;
because i want nothing between the elements of the array during join.
