PHP中的嵌套開關

Question

在我玩遊戲的網站上工作。在這個頁面上，用戶可以上傳描述一件設備的文本塊，並希望我可以通過它解析創建一個對象並將其上傳到MySQL。下面是一個例子塊：

Item:   an ethereal bracelet 
Key words: geq grey_man man ethereal bracelet geq_Guxx 
Type:   treasure 
Level:  50 
Extra flags: rot-death no-transfer 
Weight:  2 
Value:  0 
Affects:  spell-resistance by 5. 
Affects:  dexterity by 1. 
Affects:  strength by 1. 
Affects:  intelligence by 1. 
Affects:  wisdom by 1. 
Affects:  hitroll by 5. 
Affects:  constitution by 1. 
Affects:  hp by 50. 
Affects:  damroll by 10. 

這裏是在我的設備類中的函數：

public function create_eq_from_text($text) { 
     $text = trim($_POST['item']); 
     $text = explode("\n", $text); 
     foreach($text as $line) { 
      switch($line) { 
       case strstr($line, 'Item:'): 
        $this->name = trim(str_replace('Item:', '', $line)); 
        break; 
      case strstr($line, 'Key words:'): 
       $line = trim(str_replace('Key words:', '', $line)); 
       $this->key_words = $line; 
       break; 
      case strstr($line, 'Type:'): 
       $line = trim(str_replace('Type:', '', $line)); 
       $this->type = $line; 
       break; 
      case strstr($line, 'Level:'): 
       $line = trim(str_replace('Level:', '', $line)); 
       $this->level = intval($line); 
       break; 
      case strstr($line, 'Extra flags:'): 
       $line = trim(str_replace('Extra flags:', '', $line)); 
       $this->extra_flags = $line; 
       break; 
      case strstr($line, 'Weight:'): 
       $line = trim(str_replace('Weight:', '', $line)); 
       $this->weight = intval($line); 
       break; 
      case strstr($line, 'Value:'): 
       $line = trim(str_replace('Value:', '', $line)); 
       $this->value = intval($line); 
       break; 
      case strstr($line, 'physical attacks'): 
       $this->p_ac = get_number($line); 
       break; 
      case strstr($line, 'magic attacks'): 
       $this->m_ac = get_number($line); 
       break; 
      case strstr($line, 'spell-resistance'): 
       $this->saves = get_number($line); 
       break; 
      case strstr($line, 'dexterity by'): 
       $this->dex = get_number($line); 
       break; 
      case strstr($line, 'strength by'): 
       $this->str = get_number($line); 
       break; 
      case strstr($line, 'intelligence by'): 
       $this->intel = get_number($line); 
       break; 
      case strstr($line, 'wisdom by'): 
       $this->wis = get_number($line); 
       break; 
      case strstr($line, 'constitution by'): 
       $this->con = get_number($line); 
       break; 
      case strstr($line, 'damroll by'): 
       $this->dam = get_number($line); 
       break; 
      case strstr($line, 'hitroll by'): 
       $this->hit = get_number($line); 
       break; 
      case strstr($line, 'hp by'): 
       $this->hp = get_number($line); 
       break; 
      case strstr($line, 'mana by'): 
       $this->mana = get_number($line); 
       break; 
      case strstr($line, 'Damage is'): 
       $line = trim(str_replace('Damage is', '', $line)); 
       $line = str_replace('.', '', $line); 
       $this->weapon_damage = $line; 
       break; 
      } 
     } 
} 

這裏是窗體代碼：

if(isset($_POST['submit']) && !empty($_POST['item'])) { 
    $item = new Equipment; 
    $item->create_eq_from_text($item); 
    print_r($item); 
    } 

出於某種原因，唯一的開關捕捉的是strstr（'Item：'）。首先，我認爲轉換中的突破已經脫離了習慣，但我已經排除了這一點。任何人都可以將我指向正確的方向嗎？

您不能在這種情況下使用switch語句，因爲您正在尋找$ line內的子字符串。 Switch語句查找與給定變量的匹配，而不是布爾值。
