I used "0x1" here for brevity.  In real world I use gmp_powm() for
diffie-hellman key exchange with vastly larger numbers that can't be
represented as normal integers in php.

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

Do not pass hex numbers as strings. 
var_dump(gmp_powm(0x1, 0x1, 0x1)); 
 
works fine.
