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!

When called from a command-line process, this function does nothing when passed a specific header to remove, but it does nonetheless work properly when called with no arguments to remove all headers.
Thus, when unit-testing or executing in some other test harness, if the code you are testing may call `header_remove()`, with the UOPZ and XDebug extensions loaded, you could use the following in order to more effectively test that the expected headers are set [which you would do by inspecting the array returned by `xdebug_get_headers()` after running the code under test, as `headers_list()` does not work despite the headers actually being stored internally as normal]:
<?php
uopz_set_return(
'header_remove',
function($name = null) {
if ($name !== null) {
$pattern = '/^' . preg_quote($name, '/') . ':/i';
$headers = array_filter(
xdebug_get_headers(),
function($header) use($pattern) {
return !preg_match($pattern, $header);
}
);
}
// This works to remove all headers, just not individual headers.
header_remove();
if ($name !== null) {
foreach ($headers as $header) {
header($header);
}
}
},
true
);
?>
