preg_match for php for the date

How to use php to preg_match the string in the following case?

the string will be like 20150923_1111. The date format if this case would be Ymd_Hi.

Just wondering whether it would be achievable to validate the date format.

I just need to make sure the string is in digit and with the same length and does not have to validate the actual time.

It sounds like you want your regex to check if the string is 8 digits, followed by an underscore, followed by 4 digits. So, you could use preg_match like this:

if (preg_match('/^[0-9]{8}_[0-9]{4}$/', $input)) {
  // Process here
}

The ^ represents the start of the string, [0-9]{x} means look for the quantity x number of digits 0-9 in a row, and the $ represents the end of the string.
