how can i create this type of if statement?

if ($variable!='hello') {$variable='';}

how do i do this if i don't want to predefine that variable?

my example doesn't work since it doesn't initially know what $variable is. in that case, i want it to assume that if it doesn't know, give it a value of '' (nothing).

That variable can actually be valued at 'hello' since i have a form pointing to its page with that variable.

anyone can help?
