用于try-catch的PHP替代语法

[英]PHP alternative syntax for try-catch

原文 2015-07-15 01:25:12 8 2 php/ syntax

PHP has an alternative syntax for control structures ( http://php.net/manual/en/control-structures.alternative-syntax.php ) and I've been used it very often lately until I got stuck looking for an alternative syntax for try-catch. PHP为控制结构提供了一种替代语法（ http://php.net/manual/en/control-structures.alternative-syntax.php ），直到最近我一直在寻找替代语法之前，我都经常使用它试用。

Is there any alternative syntax for try-catch? try-catch是否有其他语法？ If not, does anyone know why PHP doesn't include it as one of its feature, given it has alternative for other structures? 如果不是，有谁知道为什么PHP不将它作为其功能之一包含，因为它可以替代其他结构？

2 个解决方案

There is no such alternative syntax because IMHO try/catch instruction is not a control conditional structure like if, switch,... The catch block just handles exception. 没有这样的替代语法，因为IMHO try / catch指令不是控制条件结构，例如if，switch，... catch块仅处理异常。

From php documentation : 从PHP 文档：

Code may be surrounded in a try block, to facilitate the catching of potential exceptions 代码可以放在try块中，以方便捕获潜在的异常

No, there isn't an alternative syntax for try-catch. 不，try-catch没有其他语法。 Why? 为什么？ No one's asked for it. 没有人要求它。 You can take the first step and open an RFC . 您可以迈出第一步并打开RFC 。
