PHP中的嵌套开关

Question

在我玩游戏的网站上工作。在这个页面上，用户可以上传描述一件设备的文本块，并希望我可以通过它解析创建一个对象并将其上传到MySQL。下面是一个例子块：

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. 

这里是在我的设备类中的函数：

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; 
      } 
     } 
} 

这里是窗体代码：

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

出于某种原因，唯一的开关捕捉的是strstr（'Item：'）。首先，我认为转换中的突破已经脱离了习惯，但我已经排除了这一点。任何人都可以将我指向正确的方向吗？

您不能在这种情况下使用switch语句，因为您正在寻找$ line内的子字符串。 Switch语句查找与给定变量的匹配，而不是布尔值。
