[PHP] Re: how to test string to see if it is a date or time?

[DomIntCom]

can anybody help me out with this?  I have figured out checkdate finally,
but still have nothing that will help me with time validation.

thanks,

Jeff

 I have a form that is passing a date variable, and a time variable.  I
will
 be using these for a query, and will use the date function to do some
 formatting on it.

 now, I would like to idiot proof it a bit, but can't find any functions
for
 this (hoping something similar to is_numeric exists).

 does anybody have any commands, or some code that would allow me to make
 sure a variable is a valid date or time.

 thanks,

 Jeff

explode() on the time delimiter (probably colon)
check that hour is 1-12 (or 0-23)
check that minute is 0-59
check that second is 0-59

Try this (as found on php.net)

$str = 'Not Good';
if (($timestamp = strtotime($str)) === -1) {
echo The string ($str) is bogus;
} else {
echo $str == . date('l dS of F Y h:i:s A',$timestamp);
}

[DomIntCom]

here is my solution for this...

  if (($timestamp = strtotime($_POST['sdate'])) === -1)
   die (H3The start date is not a valid date format/H3);
  if (($timestamp = strtotime($_POST['edate'])) === -1)
   die (H3The end date is not a valid date format/H3);
  if (($timestamp = strtotime($_POST['stime'])) === -1)
   die (H3The start time is not a valid time format/H3);
  if (($timestamp = strtotime($_POST['etime'])) === -1)
   die (H3The end time is not a valid time format/H3);
