What is wrong with this preg_match?

[Paul Halliday <paul.halliday@xxxxxxxxx>]

I have the following:

if (isset($argc)) {
    if ($argc == 1 || $argc > 2 || !preg_match("(\d{4}-\d{2}-\d{2})",
$argv[1])) {
        echo "\nUsage: $argv[0] <yyyy-mm-dd>\n\n";
        exit;
    } else {
        $base_date = $argv[1];
    }
} else {
    $base_date = date('Y-m-d');
}

When I run it:

 $ ./process_patches.php 201-01-01

Usage: ./process_patches.php <yyyy-mm-dd>

patches@innm2 ~/Code/Oculi $ ./process_patches.php 2011-011-01

Usage: ./process_patches.php <yyyy-mm-dd>

patches@innm2 ~/Code/Oculi $ ./process_patches.php 2011-01-011

Works..

What am I doing wrong?

Thanks!
