Thank you for taking the time to write to us, but this is not a bug. Please double-check the documentation available at http://www.php.net/manual/ and the instructions on how to report a bug at http://bugs.php.net/how-to-report.php 11213214321 overflows an integer and is converted into a negative number. The modulus operation is then performed on a negative value, hence the -1 return value.
