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!

expose_php is php.ini only!

this won't work:
ini_set('expose_php',0);

works:
header_remove('x-powered-by');

You should ini_set("expose_php", 0); or set it in your php.ini to Off, instead of using this to remove X-Powered-By header.
