Problem with writing variable to .txt extension

[Steels]

Hello everyone ,
i have this problem
i want to have the name of the .txt file to be the name of my $title variable
so for instance if my variable of $title is test then the txt file should be named test.txt file

here some code:

$filename = $titel.txt; // this isnt working ofcourse
$create = fopen($filename, "w"); //uses fopen to create our file.

someone any ideas?

Thx

$filename = $title . '.txt';
