blocking access from google chrome

[JuniorWU]

good many of my forum users complain, that does not have a good view in google chrome, the display is distorted way, you can not straighten out, then decided to block the chrome, below is the code I want to use to lock the browser, but it has to be inserted into page after page, wondering if it would have an easier way to block it

if (strstr($_SERVER["HTTP_USER_AGENT"], "Chrome")) {
	header("Location: chrome.php");
	exit;
}
