Date validation

[ghjk]

I want to validate Date in my php application. User should select a date by clicking on calander icon or typinig. I want to check whether the date is in "2008-07-01" format. How can i do that? Could some one help me?

You could use a simple regular expression for that validation.

try this:

<?php
$date_in = '2008-07-01';
list($year, $month, $day) = explode('-', $date_in);

if (checkdate($month, $day, $year)) {
  echo 'date valid.';
} else {
  echo 'date invalid';
}

try this:

<?php
$date_in = '2008-07-01';
list($year, $month, $day) = explode('-', $date_in);

if (checkdate($month, $day, $year)) {
  echo 'date valid.';
} else {
  echo 'date invalid';
}

nice, but regex would be faster.

Here's one that checks for February dates range 0-29:

preg_match("/^(19|20)?[0-9]{2}[-/ \\.]((0?[13-9]|1[012])[-/ \\.](0?[1-9]|[12][0-9]|3[01])|(0?2[-/ \\.][012]?[0-9]))$/",$variable);

if you don't care about February 30 / 31 date checking try this:

preg_match("/^(19|20)?[0-9]{2}[- /.](0?[1-9]|1[012])[- /.](0?[1-9]|[12][0-9]|3[01])$/",$variable);

please let me know if there's any problems in the first one, I hand coded it myself.
