Problen set variables in fopen

Hello, sorry i'm new to PHP and programming, but i have a simple question: I do a $template = fopen ("incdir/emplate.txt","r"); while (!feof($template)) { $output=fgets($template,256) ; $testmessage.=$output ; } and in the template.txt files there are some variables wrote down in the form: -->> $variable I want to set some values to this variables when while is running, but i only get teh clear text "$variable" in output. How can i get changed this to set the values of the vars to this??
