Transform Perl Arrays to Strings
We can use the join() function in Perl to rejoin the array elements and form one long scalar string. This function has the following syntax −
Syntax
join EXPR, LIST
This function joins the separate strings of LIST into a single string with fields separated by the value of EXPR and returns the string. Following is the example −
Example
#!/usr/bin/perl
# define Strings
$var_string = "Rain-Drops-On-Roses-And-Whiskers-On-Kittens";
$var_names = "Larry,David,Roger,Ken,Michael,Tom";
# transform above strings into arrays.
@string = split('-', $var_string);
@names = split(',', $var_names);
$string1 = join( '-', @string );
$string2 = join( ',', @names );
print "$string1\n";
print "$string2\n";Output
This will produce the following result −
Rain-Drops-On-Roses-And-Whiskers-On-Kittens Larry,David,Roger,Ken,Michael,Tom
