Transform Perl Strings into Arrays
Let's look into a Perl function called split(), which has the following syntax −
Syntax
split [ PATTERN [ , EXPR [ , LIMIT ] ] ]
This function splits a string into an array of strings and returns it. If LIMIT is specified, splits into at most that number of fields. If PATTERN is omitted, splits on whitespace. 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(',', $var_names);
print "$string[3]\n"; # This will print Roses
print "$names[4]\n"; # This will print MichaelOutput
This will produce the following result −
Roses Michael
