php验证手机号码,验证手机号码
大家都应该有这个常识,中国的手机号码都是以数字“1”开头,然后利用“0~9”10个数字组成的11位数字组合,那么我们的验证规则肯定要根据这个思路来写。
根据上面的简单思路,我们便可以写下以下的验证代码,代码如下:
<?php //本代码仅仅是提供一些思路 //距离实际应用还有一些距离 $mobile = '15858588585'; //下面的1便是手机的第一位数字必须为数字1 //[0-9]指后面的数字均为0~9的数字 //{9}这中间的9指的是手机号码除了第一位数外,其他要重复10次,刚好就是11位数了 if(!preg_match('/^1([0-9]{9})/',$mobile)) exit('您的手机号码不正确'); ?>
但上面的代码显然是不够严谨的,因为这样,即使“18888888888”这样的手机号码也能通过验证了,因此我们还要对其进行更为严格的验证,在严格之前请让我们先来看看中国常见的手机号码前三位都有那些:
移动手机号码:134、135、136、137、138、139、150、151、157(TD)、158、159、187、188
联通手机号码:130、131、132、152、155、156、185、186
电信手机号码:133、153、180、189、(1349卫通)
那么根据上面的特征,我们就可以将代码修改成这样的规则了,代码如下:
<?php function checkMobile($str) { $pattern = “/^(13|15)d{9}$/”; if (preg_match($pattern,$str)) { Return true; } else { Return false; } } //调用函数 $str = checkMobile(“15800000001″); if($str) { echo(“符合手机号码标准”); } else { echo(“不符合手机号码标准”); } ?>
上面只能骓13,15开头的,如果有新段就不行了,我们可加以修改,代码如下:
function is_mobile($str){ return preg_match("/^(((d{3}))|(d{3}-))?13d{9}$/", $str); }
这样就可以验证所有的手机号码了,整个解析思路环环相扣,针对php验证手机号码进行详细分析,得出解决方法。
以上就是为大家分享的php验证手机号码的方法,希望对大家的学习有所帮助。

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,
