Well... where shall I start...
Comparison: ==
Assingment: =
(and _not_ the other way 'round)
And then... Why would you even think about comparing to fixed
strings? You wouldn't. So I guess you'd like to send some real code
next time, so people can see what you're trying to do.
And then...
"inf" = "inf" doesn't work _at all_! It produces an error. If you
use "inf" == "inf" the result is exactly what you'd expect.
And then...
In your real code, which is something like $var = "inf", you should
use $var == "inf". If you do that, you won't have any problems.
