if you want to remove header information about php version (x-powered-by), you can use:
header_remove('x-powered-by');
alternatively, if you don't have php 5.3 installed, you can do the same thing using "header" command:
header('x-powered-by:');
don't forget the ':' character at the end of the string!

FYI: This function does not support an array or multiple entries
header_remove(array("X-Powered-By","Expires")); // doesn't work
header_remove("X-Powered-By","Expires"); // doesn't work
Spent the time verifying if it was similar to the unset() command which allows.
unset($a,$b);
