Help with plugin array and option settings

Can you write files via php on your server? I like to debug stuff by printing things to a file then looking at it after loading the page. Like sometimes I just throw in a

fwrite(fopen("output.txt", "w"), print_r($var, true));

...I think that actually shouldn't work on a "live" server ( unless you put in a path to a different directory) because the web server user usually doesn't have write access. But anyway the point is that it will probably save time if you can figure out some way to see what's going on in there.
