How to implement exception handling class in PHP

This article mainly introduces the simple exception handling class implemented by PHP, and analyzes the relevant implementation techniques of PHP's exception handling operations based on object-oriented technology based on specific examples. Friends in need can refer to the following

for details As follows:

<?php
header(&#39;content-type:text/html;charset=UTF-8&#39;);
// 创建email异常处理类
class emailException extends exception
{
}
// 创建pwd异常处理类
class pwdException extends exception
{
  public function __tostring(){
    return $this->getMessage().&#39;in file:&#39;.$this->getFile().&#39;on line:&#39;.$this->getLine();
  }
}
function reg($reginfo = null)
{
  // 依据不同错误抛出不同异常
  if (empty($reginfo) || !isset($reginfo)) {
    throw new Exception(&#39;参数非法&#39;);
  }
  if (empty($reginfo[&#39;email&#39;])) {
    throw new emailException(&#39;邮件为空&#39;);
  }
  if ($reginfo[&#39;pwd&#39;] != $reginfo[&#39;repwd&#39;]) {
    throw new pwdException(&#39;两次密码不一致！&#39;);
  }
}
// 接收不同异常，并针对性处理！
try {
  reg(array(&#39;email&#39; => &#39;1078789950@qq.com&#39;, &#39;pwd&#39; => &#39;123&#39;, &#39;repwd&#39; => &#39;1231&#39; ));
} catch (Exception $e) {
  echo $e ->getMessage();
} catch (emailException $ee) {
  echo $ee ->getMessage();
} catch (pwdException $ep) {
  echo $ep;
}
