  代码如下

  function funcMtel($str)//手机号码正则表达试

  {

  return (preg_match("/(?:13d{1}|15[03689])d{8}$/",$str))?true:false;

  }

  测试

  18678785887

  返回为

  false

  原因分析,查看了发现上面正则只能验证以13,15开头的,自然18开头的是不可以用的

  修改后

  代码如下

  function funcMtel($str)//手机号码正则表达试

  {

  return (preg_match("/(?:1[3|4|5|8]d{1}|15[03689])d{8}$/",$str))?true:false;

  }

  测试

  18678785887

  返回为

  true

  这样就成功了,

  总结经验:

  像手机号这类都会不断更新号码段了,我们在写函数时把它写成公共函数,这样就可以解决这个问题了。
