有谁知道这个PHP错误消息背后的含义？（有谁知道这个php错误消息背后的含义吗）

解析错误：语法错误,意外的T_ENCAPSED_AND_WHITESPACE,预计消息为T_STRING或T_VARIABLE或T_NUM_STRING.它来自以下代码行：

$query = ("SELECT * 
             FROM users 
            WHERE user_name = $_POST['user_name'] 
                & password = $_POST['password'] 
                & user_type = $_POST['user_type']");

外面有人知道这一切的意思吗？如果是这样,有人知道该如何处理吗？

解决方法:

采用：

$query = sprintf("SELECT u.* 
                    FROM USERS u
                   WHERE u.user_name = '%s' 
                     AND u.password = '%s' 
                     AND u.user_type = '%s' ",
                   MysqL_real_escape_string($_POST['user_name']),
                   MysqL_real_escape_string($_POST['password']),
                   MysqL_real_escape_string($_POST['user_type']) );

$result = MysqL_query($query);

c – 内部编译器错误消息的含义是什么,我该怎么办？

我正在尝试编译我的C程序,它使用MPICH和NAG C库(我使用NAG生成随机数),使用pgCC编译器.

但是,编译器给了我以下错误消息：

PGCC-S-0000-Internal compiler error. linearize: bad ili #:       0 (mpisim.C: 225)
PGCC-S-0000-Internal compiler error. gen_aili: unrec. ili opcode:       0 (mpisim.C: 225)
PGCC-S-0000-Internal compiler error. linearize: bad ili #:       0 (mpisim.C: 266)
PGCC-S-0000-Internal compiler error. gen_aili: unrec. ili opcode:       0 (mpisim.C: 266)
PGCC/x86 Linux 12.4-0: compilation completed with severe errors

我不知道这些消息是指什么.有人可以向我解释他们的意思吗？

有没有办法让我弄清楚问题线的位置？ 255(mpisim.C：225)中的255是否表示我的代码中的行号？

解决方法

内部编译器错误是编译器中的错误.没有什么可以解决编译器供应商提出的问题.

通常,ICE会在您尝试编译错误代码时发生,但编译器也可以完全想到阻塞有效的C.语言非常复杂,很难在所有可能的组合中测试每个可能的功能.

如果你设法弄清楚导致崩溃的代码行,你可以尝试用更简单的术语重写它(例如通过引入额外的局部变量或typedef).

C#：InvalidCastException误导消息背后的原因

这个特殊的问题更多的是试图看到编译器消息背后的原因而不是解决问题,但我希望它没关系.

假设我们有：

class Foo {
    public static explicit operator Foo(Bar bar) {
        return new Foo();
    }
}

Bar的实施并不重要.现在,当您尝试以下操作时,会发生异常：

object obj = new Bar();
Foo foo = (Foo)obj;

它给出了InvalidCastException,这是正确的,因为我们没有对象类型的转换运算符.但是异常消息是：

system.invalidCastException: Unable to cast object of type ‘Bar’ to type ‘Foo’

这有点误导,因为我显然可以将类型Bar的对象转换为Foo类型.我希望编译器告诉我,我基本上是在尝试构建System.Object类型的对象,而不是Bar.
我的理解是否存在缺陷？如果是这样,这种行为背后的原因是什么？

提前致谢

编辑：为了清楚,我知道如何处理这个问题,而且Foo foo =(Foo)(Bar)栏就可以了.我对错误信息本身更感兴趣.

解决方法

那么,该消息还能说什么？

如果它说“无法将类型’对象’的对象强制转换为’Foo”,那么这会产生误导并且不太有用,因为obj不是对象的实例,你也无法知道什么是obj一个例子.

另一种选择是“无法将类型为’Bar’的对象(引用为’对象’)输入’Foo’”,但这很冗长,有点令人困惑.也许它的措辞可能更好,但它仍然冗长 – 此外,您只需查看源代码即可快速找到相同的信息.

当你考虑它时,消息是有效的(即使它没有告诉整个故事) – 可以从Bar转换为Foo,但在这种特殊情况下,CLR无法执行此转换.

ios – 有谁知道这个错误意味着什么？将是脂肪和ar(1)将无法操作它

我正在使用sspullToRefresh编译我的应用程序(它是一个 Rubymotion应用程序)并继续收到此消息：

will be fat and ar(1) will not be able to operate on it

有人知道这意味着什么以及我应该如何处理它？

解决方法

似乎问题已得到解决.
