Regex - Date validation 1

[Alphabin]

I know it may have been already discussed in the past, but I need a simple regex to validate dates in the following format: yyyy-mm-dd


Thank you

a simple regex can't validate a date, merely the format of date

There are times when a regex shouldn't be used, and this looks like one of 'em, but I am prepared to eat humble pie

What do you mean by validate? If you simply mean 'make sure it is 4 digits followed by a dash followed by 2 digits followed by a dash followed by 2 digits' then a simple regex would work fine. If you want to get into checking to make sure that the second two digits are between 1 and 12 or that if the second two digits are 2, then the last two digits must be between 1 and 28 unless the first 4 digits are divisible by 4 then between 1 and 29, then a regex will still work, but it would be easier IMO to split the string and validate each piece.

I'm simply looking basic regex to check if the date as the corrent format xxxx-xx-xx (x = digits) I don't wanna check if the numbers are valid or not...

Thank you guys

I think its as simple as

if ($date=m/dddd-dd-dd/) {
...
}

but i could be wrong

I would have thought:
m/\d{4}-\d{1,2}-\d{1,2}/

But it will depend on if the day and month values will be padded or not.
