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);
