Remove values from an array in Perl

Let's say you have an array of fruit that contains apple, banana, orange, and grape.

@fruits = qw(apple banana orange grapes);


Splice can be used to remove a value from the array. In this example, every occurence of "grape" will be removed from @fruits.

# Count the number of values in the array
my $count = scalar @fruits;

# Set the index to zero
my $index = 0;

# Find every occurence of the value that you want to remove from the array
$index++ until $fruits[$index] eq "grape" or $index == $count;

# Remove every occurence from the array
splice (@fruits, $index, 1);
