How to transform strings to arrays in Perl using split() method

Overview

We can transform a string to an array in Perl the split() method. It only takes two parameters to start the transformation.

Syntax

split(at, str)

Parameters

at: This specifies where to start the transformation.

str: This is the string we want to transform to an array.

Return value

The value returned is an array.

Example

# create some strings
$name = "Okwudili Onyejiaku";
$quote = "Edpresso-is-great!";
# transform strings to array
@arr1 = split(" ", $name);
@arr2 = split("-", $quote);
# print results for @arr1
print "First Array:\n\n";
for (my $index = 0; $index <= $#arr1; $index++) {
  print("Element $index is $arr1[$index]\n");
}
# print results for @arr2
print "\nSecond Array:\n\n";
for (my $index = 0; $index <= $#arr2; $index++) {
  print("Element $index is $arr2[$index]\n");
}

Explanation

  • Lines 2–3: We create two strings that we want to transform.
  • Line 6: We transform the string ＄name to an array at space (" ") and store the result in array @arr1.
  • Line 7: We transform the string ＄quote to an array at hyphen ("-") and store the result in array @arr2.
