PHP日期格式正则表达式检查
问题描述：
我正在尝试使用PHP正则表达式验证日期字段 YYYYMMDD 。我尝试过这样的事情
i am trying to valdiate the date field "YYYYMMDD" using PHP regex. I tried something like this
/([0-9]{4})([0-9]{2})([0-9]{2})/
，但在此示例中，它将接受任何两位数字，例如MM或DD的01-99，但我希望MM的01-12和DD的01-31。对此有任何建议吗？
but in this one, it's going to accept any two digits like 01-99 for MM or DD, but i am looking to have something for 01-12 for MM and 01-31 for DD. Any advise on doing this?
谢谢
答
而不是正则表达式，您还可以拆分字符串并使用 检查日期 以查看日期是否有效。
Instead of regular expressions you can also split the string and use checkdate to see if the date is valid.
