Perl: convert character array to string

Previously I have posted a topic related to convert a string into character array into Perl here perl-string-to-character-array

I have found people are searching my blog to find the other way. I mean they have the character array, now they want to convert it into string back. Here is the example to do such things.

use strict;

## Convert String into array
my $str = " Perl: convert character array to string ";
my @char_array = split(//,$str);

## Make string from each value of char separated by string
$str = "@char_array";
print "$str\n";
## Replace the Extra separating spaces with blank
$str =~ s/(.)\s/$1/seg; ## Simple Regex
print "$str\n";

When the above code will execute, below will happen

Array to string with separated by space.
  P e r l :   c o n v e r t   c h a r a c t e r   a r r a y   t o   s t r i n g  
Now squeeze the extra spaces will make above string into.
