[SOLVED] Date Regex

[bigdspbandj]

When I use this date regex:

 

'(0[1-9]|1[012])[- /.](0[1-9]|[12][0-9]|3[01])[- /.](19|20)[0-9]{2}'

 

I get this error:

 

Warning: preg_match() [function.preg-match]: Unknown modifier '[' in /Users/bigdspbandj/Sites/optimal_web/customer_tracking/submit_job_mgmt_trust.php on line 13

 

 

I am trying to match a date string that doesn't match mm/(or -)dd/(or -)yyyy.

 

Anyone have one handy?

<?php
if (preg_match('%\A(?:^(0[1-9]|[12][0-9]|3[01])[- /.](0[1-9]|1[012])[- /.](19|20)[0-9]{2}$)\Z%', $date))
{
echo "valid date";
} else {
echo "Invalid date";
}
?>

<?php

fyi, the failure of the original regex was due to an incorrect pattern. a fixed version might be

 

$pattern = '/(0[1-9]|1[012])[- \/.](0[1-9]|[12][0-9]|3[01])[- \/.](19|20)[0-9]{2}/';

this may work better..

ie no 31 days in Feb

<?php
$date = "10/19/2007";
$result = "InValid";
if (preg_match('%(0[1-9]|1[012])[- /.](0[1-9]|[12][0-9]|3[01])[- /.](19|20)[0-9]{2}%', $date, $regs))
{
if (checkdate($regs[1], $regs[2], $regs[3]))
{
	$result = "Valid";
}
}
echo $result;

?>
