我做了以下脚本:
print "Will accept input until EOF";
while(defined($line = <STDIN>)){
print "Input was $line \n";
if(chomp(@line) eq "end"){
print "aha\n";
last;
}
}
我有两个问题:
end控制台我不能看到aha并break从环路(last是相等的break权)？ EOF阻止while循环的关键组合？我以为它在ctrl+D,Windows但它不起作用.我在我的模型中使用此代码,
public function registration(){
$name = 'Foo';
$city = 'Bar';
$this->User->save(
array(
'name' => $name,
'city' => $city
)
);
}
但插入时会出现致命错误
"Error: Call to a member function save() on a non-object
File: C:\xampp\htdocs\blogs\app\Model\User.php"
如何插入？

我搜索了一个很好的答案,但我还没有得到适当的答案.谁知道答案,请回复.我在下面发布了一些代码.
