与模具PHP的问题（）

Question

所以，我有这样的代码：

 } else { 

      $photograph_moderation = new PhotographModeration($this->photograph_id); 
      $photograph_moderation->purgePhotograph(); 

      //eventually take to an error page 
      die('image is not big enough to upload'); 

     } 

的purgePhotograph（）函数被调用时，适当满足此条件，但该脚本永远不会出现死。死亡是不是有理由在这里召唤？ purgePhotograph（）也没有脚本查杀命令。

这里的purge_photograph功能：

public function purgePhotograph() { 

    $db = Connect::connect(); 
    $photograph_id = $db->real_escape_string($this->photograph_id); 

    $query = "SELECT * from photographs WHERE id='{$this->photograph_id}'"; 
    $result = $db->query($query); 
    $photograph = $result->fetch_assoc(); 

    if ($photograph['location']) 
    unlink($photograph['location']); 

    if ($photograph['thumbnail_location']) 
    unlink($photograph['thumbnail_location']); 

    if ($photograph['watermark_location']) 
    unlink($photograph['watermark_location']); 

    if ($photograph['xsmall_location']) 
    unlink($photograph['xsmall_location']); 

    if ($photograph['small_location']) 
    unlink($photograph['small_location']); 

    if ($photograph['medium_location']) 
    unlink($photograph['medium_location']); 

    if ($photograph['large_location']) 
    unlink($photograph['large_location']); 

    if ($photograph['xlarge_location']) 
    unlink($photograph['xlarge_location']); 

    if ($photograph['xxlarge_location']) 
    unlink($photograph['xxlarge_location']); 

    if ($photograph['xxxlarge_location']) 
    unlink($photograph['xxxlarge_location']); 

    $query = "DELETE from photographs WHERE id='{$this->photograph_id}'"; 
    $result = $db->query($query); 

    $query = "DELETE from photograph_tags WHERE photograph_id='{$this->photograph_id}'"; 
    $result = $db->query($query); 

} 

Answer 1

也许现在是安装php debugger module并进入相关代码的时候了。
xdebug和例如作为前端的netbeans工作得不错。

Answer 2

检查purgePhotograph（）返回。也许它有一个死循环或需要很长时间。

Answer 3

尝试将其放入try/catch块。 也许有些东西在死亡可以执行之前抛出异常。

您是否收到任何错误？

Answer 4

哇，问题是purgePhotograph（）从来没有一个返回1;最后。我不知道这是执行以下行所必需的。
