How to Iterate Over an Array in Perl - Step by Step Examples

How to Iterate Over an Array in Perl ?

To iterate over an array in Perl, you can use foreach loops or array index iteration.

In this example,

We create an integer array named @numbers with some values.
We use a foreach loop to iterate over each element of the array and print the elements.

@numbers = (1, 2, 3, 4, 5);
foreach my $num (@numbers) {
  print "$num\n";
}

In this example,

We create a string array named @fruits with some values.
We use an array index to iterate over each element of the array and print the elements.

@fruits = ("apple", "banana", "cherry");
for my $i (0 .. $#fruits) {
  print "$fruits[$i]\n";
}

apple
banana
cherry
