php try ... else [英] php try ... else

问题描述

我需要在PHP中使用类似的东西到 try ... else 知道try块是否正确执行，当块正确执行时，将打印一条消息。

解决方案

您可以使用 try {} catch（）{} 和 throw 。请参阅 http://php.net/manual/en/language.exceptions.php

  try {
 $ a = 13/0; //应该抛出异常
} catch（异常$ e）{
 echo'捕获异常：'，$ e-> getMessage（），\\\
; 
} 
  

或手动：

  try {
 throw new Exception（我不想尝试！）; 
} catch（Exception $ e）{
 echo'捕获异常：'，$ e-> getMessage（），\\\
; 
} 
  

Is there something similar in PHP to the try ... else in Python?

I need to know if the try block executed correctly as when the block executed correctly, a message will be printed.

解决方案

You can use try { } catch () { } and throw. See http://php.net/manual/en/language.exceptions.php

try {
    $a = 13/0; // should throw exception
} catch (Exception $e) {
    echo 'Caught exception: ',  $e->getMessage(), "\n";
}

or manually:

try {
    throw new Exception("I don't want to be tried!");
} catch (Exception $e) {
    echo 'Caught exception: ',  $e->getMessage(), "\n";
}
