<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> 
<html xmlns="http://www.w3.org/1999/xhtml">

<title>自定义异常处理类</title> 
</head> 
<body> 
<?php 
class TelException extends Exception{      //定义TelException类，继承Exception类 
  public function errorTel(){         //定义方法返回错误信息 
  $errorMsg = "出错原因：".$this->getMessage()."不是一个合法的电话号码"; 
  $errorMsg .="<br>"; 
  $errorMsg .="错误文件路径：".$this->getFile(); 
  $errorMsg .="<br>"; 
  $errorMsg .="错误代码行号：".$this-> getLine();  
  return $errorMsg; 
  } 
} 
function check_tel($tel){              //自定义函数验证电话号码格式是否正确 
  $checkphone="/^13(\\d{9})$/";    //定义验证手机号码的正则表达式 
  $counts=preg_match($checkphone,$tel);      //执行验证操作 
  return $counts;                 //返回验证结果 
} 
$tel = "133891gfj";               //定义被验证的电话号码 
/* 
  通过自定义异常处理类返回错误提示 
*/
