Homephp教程php手册js和php邮箱地址验证的实现方法

这篇文章主要介绍了js和php邮箱地址验证的实现方法,有需要的朋友可以参考一下

邮箱地址验证有很多方法。在浏览器端,js邮箱验证可以通过正则表达式检测。

比如:

复制代码 代码如下:


function isEmail(email) {
    return /^((([a-z]|\d|[!#\$%&'\*\+\-\/=\?\^_`{\|}~]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])+(\.([a-z]|\d|[!#\$%&'\*\+\-\/=\?\^_`{\|}~]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])+)*)|((\x22)((((\x20|\x09)*(\x0d\x0a))?(\x20|\x09)+)?(([\x01-\x08\x0b\x0c\x0e-\x1f\x7f]|\x21|[\x23-\x5b]|[\x5d-\x7e]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])|(\\([\x01-\x09\x0b\x0c\x0d-\x7f]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF]))))*(((\x20|\x09)*(\x0d\x0a))?(\x20|\x09)+)?(\x22)))@((([a-z]|\d|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])|(([a-z]|\d|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])([a-z]|\d|-|\.|_|~|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])*([a-z]|\d|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])))\.)+(([a-z]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])|(([a-z]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])([a-z]|\d|-|\.|_|~|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])*([a-z]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])))$/i.test(email);
}

调用很简单:

复制代码 代码如下:


if (isEmail('youremail@yourdomain.com')){ console.log('This is email is valid'); }

如果是进行服务器端验证。像php,则最简单的莫过于:

复制代码 代码如下:


/*
 * 邮箱地址合法性验证
 */

function isEmail($mail_address) {
    return filter_var($mail_address, FILTER_VALIDATE_EMAIL);
}

但是这个件事也可以整得复杂。

像这位。他建立起一整套的邮箱地址验证网站体系。估计很少人这么干。

说实话,不得不佩服。
