I dont fully understand the need for this?

This code is great if you wish to display one set of output for Chrome, and another for (say) Firefox or Internet Explorer.
Thanks for providing this code… it really saved me today!

Thx! This was just what i needed, and very simple to.
I use it because chrome of some reason wants a differen charset, than IE, and FF in some cases. (Too display special characters, when using AJAX, PHP, HTML, and CSS).
Thx alot!

May be handy but strstr is significantly faster and more efficient than using eregi.
You should never use regular expression functions unless you’re using regular expressions.
Also this eregi is depreciated as of PHP 5.3.0 (php.net).

Thanks for the code – works perfectly!

This code:
return(eregi(“chrome”, $_SERVER['HTTP_USER_AGENT']));
should be:
return(preg_match(“/applewebkit/i”, $_SERVER['HTTP_USER_AGENT']));
First, the eregi function calls in PHP are deprecated and shouldn’t be used.
And second, the check should be for ‘applewebkit’, since it will match other browsers like ‘chromium’, ‘safari’, ‘midori’, etc. These browsers use the same rendering engine as chrome and will suffer from whatever problems one is working around by these conditional checks.
Peace
