Does PHP's filter

After reading various posts I decided not to use REGEX to check if an email is valid and simply use PHP's inbuilt filter_var function. It seemed to work ok, until it started telling me an email was invalid because I had a number in it. ie name@domain.com works, while name2@domain.com doesn't.

PHP的过滤器

阅读各种帖子后,我决定不使用REGEX来检查电子邮件是否有效,并简单地使用PHP的内置filter_var函数。 它似乎工作正常,直到它开始告诉我一封电子邮件是无效的,因为我有一个数字。 即name@domain.com工作,而name2@domain.com不工作。 我错过了什么,或者是filter_var($email, FILTER_VALIDATE_EMAIL)真的很无效吗? PHP 5.3.3过滤器代码中使用的正则表达式基于Michael Rushton关于电子邮件地址验证的博客。 它似乎适用

Update whole page on Ajax request
