hi,fayland~
改成:
#!/usr/bin/perl
my $error = &validate();
if (%$error) {
print 'error';
} else {
print 'ok';
}
sub validate {
my $error= { };
return $error;
}
如何?
呵呵,昨天列表里比较热闹啊呵呵,可惜昨天我忙了一通宵PB课程设计,到今早4,5点才睡觉.
验证码那个我很早以前也去 perl 的新闻组问过,没人给出解决方法呵呵,不过后来知道了有些简单的验证码,通过分析其源码,是有规律可寻的,不过加上变形,干扰色之后就复杂了...应该没有一个统一的解决方法吧?

会输出 error. 怎么写比较好?
