# 多异常捕获处理

一个catch语句块现在可以通过管道字符(|)来实现多个异常的捕获。 这对于需要同时处理来自不同类的不同异常时很有用。

```php
<?php
try {
    // some code
} catch (FirstException | SecondException $e) {
    // handle first and second exceptions
}
```

## 解说：

在以往的 `try ... catch` 语句中，每个 `catch` 只能设定一个条件判断：

```php
<?php
try {
    // Some code...
} catch (ExceptionType1 $e) {
    // 处理 ExceptionType1
} catch (ExceptionType2 $e) {
    // 处理 ExceptionType2
} catch (\Exception $e) {
    // ...
}
```

新的实现中可以在一个 `catch` 中设置多个条件，相当于或的形式判断：

```php
<?php
try {
    // Some code...
} catch (ExceptionType1 | ExceptionType2 $e) {
    // 对于 ExceptionType1 和 ExceptionType2 的处理
} catch (\Exception $e) {
    // ...
}
```

对于异常的处理简化了一些。
