输出取决于当前URL的numrows

Question

有谁知道以下陈述应该如何？我尝试过多个结构，比如while循环和switch语句，但我无法弄明白。我知道下面的代码是完全错误的，只是想展示我想要的东西

if($numrows > 0)
  {
    if($this->currentURL() == 'http://localhost/webshop/public/index.php?page=login.php')
      {
        $this->redirect();
      }
  }
else
  {
    echo "Wrong Username or Password!";
  }
if($numrows > 0)
  {
    if($this->currentURL() == 'http://localhost/webshop/public/index.php?page=register.php')
      {
        echo "Already in use!";
      }
  }
else
  {
    $this->insertRows();
  }

我猜你希望逻辑是这样的，

 if($numrows > 0)
  {
      if($this->currentURL() == 'http://localhost/webshop/public/index.php?page=login.php')           
          $this->redirect();   
      else if($this->currentURL() == 'http://localhost/webshop/public/index.php?page=register.php')  
              echo "Already in use!";                 
          else      
              echo "Wrong Username or Password!";    
  }
  else         
      $this->insertRows();
