inbuilt PHP function to check date and time.

Hello Friends,
There is a PHP function checkdate to check if a date is a valid
Gregorian date.
Is there any such function to check for a valid time like something in
hh:mm:ss format? If not, can we use any existing date and time
functions to validate a time string like '15:45:56'?

I am unable to get an answer. If anyone knows the answer, it would be
very grateful.

Thanks you for reading this post.

Sincerely,
Wizard.

It's easy enough to write such a function. You could split the string
with explode() and then check its three parts for the correct ranges
(0-23, 0-59, 0-59).
