我想在这个PHP脚本中抛出异常或错误？ [英] Would I want to throw an exception or an error in this PHP script?

问题描述

我有一个运行数据库查询的PHP脚本。现在，如果查询失败，应该触发错误还是抛出异常？我注意到，如果我做了后者，脚本执行将在面临异常之后停止。

我的代码如下：

  if（！$ this-> connection [0]  - > query（$ this-> query））
 throw new Exception（$ this- >连接[0]  - >错误）; 
  

在这种情况下（失败的查询）使用异常有什么利弊？ p>

解决方案

取决于您的一般错误处理策略和传递给此函数的查询。投掷异常本身就是一个很好的主意，嗯，如果被抓到某个地方并被处理。

I have a PHP script that runs database queries. Now, if a query fails, should I trigger an error or throw an exception? I noticed that if I do the latter, the script execution will stop after facing the exception.

My code is as follows:

if (!$this->connection[0]->query($this->query))
    throw new Exception($this->connection[0]->error);

What are the pros and cons of using exceptions for this kind of cases (failed queries)?

解决方案

depends on your general error handling strategy and the queries passed to this function. Throwing Exceptions itself is a very good idea, IMHO, if they are caught somewhere and processed.
