Php case sensitivity

I very new to PHP, as in just started messing around with a scipt an hour ago, and I need some help (already) here is the problem

my code is like this
if ($sysdat=='other') echo "Example Other";

but incase of a misstype I want the case sensitivity removed, the only way I can think of doing it is

if ($sysdat=='other' || $sysdat=='Other' || $sysdat=='OTher' || $sysdat=='OtHer' (ect ect... ) echo "Example Other";

is there a way I can have it assume that the case in nonimportant?

There's an easy way to do this... There's a function strtolower() (also a strtoupper) that will change any string to lowercase. So your code would look like this:

if (strtolower($sysdat)=='other') echo "Example Other";

Hope this helped.

so even if it is typed OtHer it will change it to other, then compare it to 'other', ill test it right now, if thats wrong ill know in a bit

it works, thanks man
