expose_php is php.ini only!
this won't work:
ini_set('expose_php',0);
works:
header_remove('x-powered-by');
(PHP 5 >= 5.3.0, PHP 7)
header_remove — 删除之前设置的 HTTP 头
name要移除的头名称。
Note: 参数不分大小写。
没有返回值。
Example #1 取消指定的头
<?php
header("X-Foo: Bar");
header("X-Bar: Baz");
header_remove("X-Foo");
?>
以上例程的输出类似于：
X-Bar: Baz
Example #2 取消之前全部指定的头
<?php
header("X-Foo: Bar");
header("X-Bar: Baz");
header_remove();
?>
以上例程的输出类似于：
本函数会删除所有 PHP 设置的头， 包括 Cookie、Session 和 X-Powered-By。
Note:
数据头只会在SAPI支持时得到处理和输出。

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.
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!
