If the purpose of @emp and @fields is to restrict the output to just those, then you can use them to filter.

#!/usr/bin/perl
use warnings;
use strict;

use Data::Dumper;

my @emp    = ('riya','vinoth');
my @fields = ('age','company','call','address','country','name');
my %nameh  = map { $_, 1 } @emp;
my %fieldh = map { $_, 1 } @fields;

my @array = ( 'name riya',
              'age 34',
              'company xxxx',
              'fax 8765432109',
              'name vinoth',
              'age 25',
              'call 12345678',
              'company xxxx',
              'address asdd',
              'country Ind',
            );

my %hash;
my $name;
while (@array) {
    my $line = shift @array;
    if (my ($field, $value) = $line =~ /^(.*) (.*)/) {
        $name = $value if 'name' eq $field;
        $hash{$name}{$field} = $value if ($nameh{$name} && $fieldh{$fi
+eld});
    } else {
        warn "Invalid line '$line'.\n";
    }
}

print Dumper \%hash;

The output will omit the fax field I added to riya's data because it was not found in @fields.

Update: added name to list of fields! This is what comes of not testing your code.
