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。
