See more ULID/UUID Examples

Checks to see if a ULID is valid.

Important: Chilkat's ULID functionality was introduced in v9.5.0.94.

Perl

use chilkat();

$dt = chilkat::CkDateTime->new();

# A ULID must be exactly 26 chars in length,
# and is composed of the following chars: 0123456789ABCDEFGHJKMNPQRSTVWXYZ
# Note: The ULID alphabet excludes the letters I, L, O, and U

# Here's a valid ULID
$ulid = "01GRGCH4J88RECEN4D4VK4F629";
$valid = $dt->UlidValidate($ulid);
print "valid: " . $valid . "\r\n";

# Here's an invalid ULID
$ulid = "71GRGxx4Jr8RECEN4D4VK4F62!";
$valid = $dt->UlidValidate($ulid);
print "valid: " . $valid . "\r\n";
