Question

I m 相对而言,是PHP的一个完整的新项目。我的背景是C/C++和C#.Im试图反对将一些简单的PHP代码定位为导向,但Im却做了一些错误的事情。

班级代码:

class ConnectionString
{
  public $String = "";
  public $HostName = "";
  public $UserName = "";
  public $Password = "";
  public $Database = "";

  function LoadFromFile($FileName)
  {
    $this->String = file_get_contents($Filename);
    $Values = explode("|", $this->String);
    $this->HostName = $Values[0];
    $this->UserName = $Values[1];
    $this->Password = $Values[2];
    $this->Database = $Values[3];
  }
}

守则:

$ConnectionString = new ConnectionString();
$FileName = "db.conf";
$ConnectionString->LoadFromFile($FileName);
print( <p>Connection Info:   . $Connection->String .  </p> );

在<代码>上出现一处错误的Im file_get_contents($Filename)上称:Filename不能空出<>。如果我用硬码表示,档案名称代替零美元,那么我就拿到所有空洞。

我没有哪一个简单的概念?

Answer 1

You ve got the case wrong:

file_get_contents($Filename);

应当

file_get_contents($FileName);

您请查阅通知,无论是在您的网址上,还是使用/error_ reporting()。

Answer 2

购买力平价中的变数对个案敏感。页: 1 关于购买力平价变量的更多信息:

您今后可以做一些事情来避免这一问题:

Use an IDE, such as Eclipse PDT, that support auto-completion of variables.
Configure error_reporting to display all types of errors (E_ALL).

Answer 3

3. 可变案件敏感性:

function LoadFromFile($FileName)
{
   $this->String = file_get_contents($Filename); // This should be $FileName!

Answer 4

$this->String = file_get_contents($FileName);

页: 1 姓名:<>。

Answer 5

 $this->String = file_get_contents($Filename);

在这一行文上,你写了Filen美分,应当是FileN。
