header_remove — Remove previously set headers
$name
] )Removes an HTTP header previously set using header().
nameThe header name to be removed.
Note: This parameter is case-insensitive.
No value is returned.
Example #1 Unsetting specific header.
<?php
header("X-Foo: Bar");
header("X-Bar: Baz");
header_remove("X-Foo");
?>
The above example will output something similar to:
X-Bar: Baz
Example #2 Unsetting all previously set headers.
<?php
header("X-Foo: Bar");
header("X-Bar: Baz");
header_remove();
?>
The above example will output something similar to:
This function will remove all headers set by PHP, including cookies, session and the X-Powered-By headers.
Note:
Headers will only be accessible and output when a SAPI that supports them is in use.
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.
