数据存储在@emailaddresses中,如下所示:
$VAR1 = { 'email' => 'abc@google.com' };
$VAR2 = { 'email' => 'cde@google.com' };
$VAR3 = { 'email' => 'efg@google.com' };
$VAR4 = { 'email' => 'hij@google.com' };
当我打印@emailaddresses(print @emailaddresses)时,它会打印HASH(0x...)
而不是数组中的值。如何打印值?
答案 0 :(得分:1)
只需遍历您的阵列并打印出每个地址的“电子邮件”值:
my @emailaddresses = ...;
for my $addr ( @emailaddresses ) {
print $addr->{email}, "\n";
}
更好的是,将此逻辑包装在一个函数中:
sub print_email_addresses {
my @addresses = @_;
for my $addr ( @addresses ) {
print $addr->{email}, "\n";
}
}
